MSC One Provides TEN TECH LLC Access to MSC's Complete CAE Platform

Overview:

MSC Software pioneered many of the technologies that are now relied upon by the Aerospace industry to analyze and predict stress and strain, vibration & dynamics, acoustics, and thermal analysis in their flagship product, MSC Nastran. Similarly, MSC Marc and MSC Adams are highly regarded as industry-leading applications for non-linear simulation and kinematics, respectively.

TEN TECH LLC, a Los Angeles based engineering consulting firm, conducts complex engineering Finite Element Analysis. As subject matter experts in shock, vibration and thermal analysis for the Aerospace & Defense Industry, TEN TECH LLC relies heavily on MSC solutions. The types of products and applications TEN TECH is involved with share a common characteristic: field failure is never an option. To validate these designs, complex multi-physics analyses and high-performance solvers that provide great accuracy are required. TEN TECH LLC being a Small Business, high-end CAE software procurement is always a delicate balancing act as high performance and accuracy comes at a hefty premium. At least it did until now: enter MSC One.

MSC One is an expanded products token system that allows companies to take advantage of the breadth and depth of MSC Software’s simulation portfolio within a flexible token-based licensing system. Offered on an annual subscription basis, MSC One provides efficient implementation and access to a suite of multidisciplinary engineering software tools.

For TEN TECH LLC, the ability to easily access the extensive MSC One product portfolio, including all of MSC’s core products such as MSC Nastran, Adams and Marc, but also Sinda and SC/Tetra for thermal and CFD analysis was an easy choice. Access to such a variety of tools through a “check-in, check-out” token system, allows the team at TEN TECH to solve a multitude of their clients’ vibration, non-linear, thermal and CFD problems for a fraction of the cost typically incurred.

Recently, TEN TECH LLC’s Structural Mechanics Group has been actively involved in the development of telescope structures, providing Finite Element Analysis expertise for the design validation of the telescope structure supporting the Polarization of Background Radiation telescope array experiment (POLARBEAR-2).

Funded by the Simons Foundation, POLARBEAR-2 is an international collaborative effort including 8 countries, and 20 institutions. Based in Chile’s Atacama Desert, the Simons Array, comprised of three polarization of background radiation telescopes, will probe the skies in search of proof of inflation, the hypothetical moment following the Big Bang.

“We heavily relied on MSC Apex and MSC Nastran to perform these complex structural analysis tasks. MSC One made our life much easier than with our traditional workflow” - William Villers, CTO & Director of Engineering at TEN TECH LLC.

Results Validation:

The TEN TECH team was able to quickly mesh and run FEA on a very large and detailed model of a complex assembly, starting from native CAD files. Apex allowed the team to proceed with incremental analyses of subassemblies and build a very large and complex model “right the first time”. With Apex, the engineers shortened their “CAD to FEM to Analysis” time by 25%-30% compared to their traditional workflow process. At the same time, they delivered a high fidelity, reliable model to their client.

MSC Nastran’s high performance was highlighted throughout the entire project: through its ultra-fast iterative solver and GPU-accelerated processing for linear statics, to Automated Component Modal Synthesis (ACMS) and Distributed Memory Parallel (DMP) solver for large dynamics problems, MSC Nastran performed flawlessly and delivered the highly accurate results required to achieve the proper confidence level in the design.

TEN TECH plans to further utilize MSC’s products through MSC One, including Sinda, Adams, and MSC Nastran. The price of MSC One gives the TEN TECH team the financial freedom they need to use MSC Nastran and other products.

MSC帮助斯堪尼亚公司实现卡车舱室降噪

Overview:
在考虑购买车辆或驾驶车辆时,是否能有愉悦的驾驶体验至关重要;对于购买卡车的公司和卡车驾驶员而言,这也关系到个人健康和生产效率。大多数的卡车驾驶员每天至少要在驾驶室里工作8个小时。据了解,当长期处在充斥着高分贝噪音或者令人不适的声音的工作环境中,驾驶员易过度疲劳,诱发健康问题。因此,对于卡车制造商来说,设计新产品时最关键的是,要通过精心设计,降低驾驶室噪音,使降噪效果远远优于客户要求,从而能为驾驶员提供最优越的驾驶体验。作为世界卡车制造商领导者之一的斯堪尼亚公司生产各类优质卡车,其产品以超高舒适性、出色性能比著称。斯堪尼亚公司的整车声学部致力于通过降低舱室噪音级,提升隔音质量,从而尽可能满足驾驶员对降噪的需求。斯堪尼亚公司通过开展广泛测试,并引入声振模拟等新手段,从而实现对驾驶舱室降噪性能的优化。为此,斯堪尼亚开发团队选择使用Actran软件,来提升他们的设计水平、缩短设计时间。
Challenge:
随着法律法规和客户对新型卡车的设计要求越来越严格,制造商需要研发出新的方法,并形成更加稳固和有效的设计流程。在舱室噪音方面,“斯堪尼亚公司围绕噪音检测和测试开展了大量工作。”整车声学部高级工程师佩尔·奥洛夫·贝里隆德说,“我们打算进行更多的仿真工作。”佩尔·奥洛夫补充道。为了重现物理环境中的声音,斯堪尼亚团队需要了解都有哪些噪音源,并且对各种噪音如何影响舱室噪音级进行判定。“两年多来,多个部门间开展了大量的跨功能仿真模拟项目,从而对舱室噪音形成了完整的概念。”佩尔·奥洛夫说,“我们想通过调整不同噪声源的贡献量达到声学设计的目的。”整车声学部首先需要降低车辆舱室噪音的主要来源。研究发现,其主要噪音源是风噪、动力总成噪音和轮胎滚动噪音。而后,他们判定出了每种噪音源的典型频率。在获取这一重要信息后,佩尔·奥洛夫和其团队接下来就要寻找软件解决方案,即利用软件来预测主噪音源以及对舱室噪声的贡献。

MSC Software helps Scania Reduce Cabin Noise in Trucks

Overview:

Having a pleasant driving experience is a key determinant when purchasing or driving a vehicle. For companies buying trucks and for truck drivers, it is also a matter of health and productivity. Most drivers spend more than 8 hours a day in the truck cabin. High noise levels or unpleasant sounds in a working environment are known to cause excessive fatigue and health problems. It is therefore crucial for truck manufacturers to carefully design their new products and shape the cabin noise to go beyond the requirements of their customers, and propose the most enjoyable driving experience possible.

With a wide range of premium trucks, Scania, one of the world’s leading truck manufacturers naturally aims at designing trucks with outstanding comfort and performance. Scania’s Complete Vehicle Acoustic Department is focused on getting their vehicles up to speed with today’s drivers’ expectations by addressing the level and quality of cabin noise in their vehicles. The development for more optimized cabins is supported by extensive testing and the introduction of new methods based on vibro-acoustic simulations. For this endeavor, Scania’s development team chose to use Actran, a product of FFT, an MSC Software Company, to improve their designs and shorten their design cycles.

Results Validation:

Scania aims to increasingly utilize Actran’s simulations results to compare different designs and define the design directions early in the product development cycle, without the need for physical testing. To support this decision-making process, a listening studio was built at Scania. The studio is similar to that of a professional mixing studio. It encompasses a 7.1 surround system for sound and is designed to produce exactly the same listening experience for anyone who is seated in the center of the room. During subjective evaluation sessions, Per-Olof conveys to his fellow colleagues his findings based on his simulations. He combines test and simulation data to replicate the environment of driving an actual truck. This process helps managers to make important decisions, which will affect the design of the cabin. “It is a very different response from management when you can play a sound and they can have this subjective experience,” Per-Olof said. “It’s not really possible to understand from a graph what you will hear in the truck,” he explained.

With the use of Actran in this new simulation process and the subjective evaluations allowed by the listening studio, Scania now has all the tools needed to improve its customer driving experience even further, while having a more efficient design process.

MSC软件协助巨型麦哲伦望远镜探索宇宙

Overview:
宇宙来自何方?许多著名的科学家如伽利略、哥白尼、爱因斯坦等,穷尽了毕生的精力试图解答这个永恒的问题。直到今天,探索宇宙的起源仍然是个热门话题。为此,巨型麦哲伦望远镜的工作团队建起了一部200英尺高的巨型望远镜,希望它能有助于解答那些困扰科学家和科幻爱好者的问题,如:宇宙中是否还存在其它生命?最初的星系是怎么形成的?宇宙最终将走向何方?巨型麦哲伦望远镜无疑最适合这方面的研究,相比其它天文望远镜,它能收集更多的光,而且有着极高的分辨率(目前天文望远镜中最高)。该项目受到了Astronomy Australia(澳大利亚天文研究)有限公司、卡内基天文台、哈佛大学以及全球其它一些顶尖大学和研究机构的资助。考虑到巨型望远镜结构的复杂性、镜片装置以及运行中的移动等因素,巨型麦哲伦望远镜组织的工程师团队使用MSC软件的模拟工具——MSC Apex,缩短了设计时间,同时简化了仿真工作流程。
Challenge:
巨型麦哲伦望远镜的安置地点为拉斯坎帕纳斯天文台,位于智利一座山的山顶。这里远离人口聚集地区,气候干燥,是地球上光污染最少的地区之一。独一无二的天空黑度和海拔使该天文台成为了一个完美的天文观测地点。 虽然该山顶有着广阔的视野,在观测方面有很大优势,但智利频繁发生震级不小的地震给工程师们的工作带来了挑战。巨型麦哲伦望远镜将设立在一幢22层的巨大建筑中,该建筑必须能抵御里氏震级8.0以上级别的地震冲击,这意味着精密而准确的测试是至关重要的。此外,由于较高的海拔,风速带来的影响也不可忽视。 除了环境因素,望远镜自身的设计和测试也是个极大的难题。巨型麦哲伦望远镜由不同尺寸的多个动态、可移动单镜组成。主镜面的直径达到了25米,多个辅镜的面积总和达到了4000平方英尺。望远镜的建筑为穹顶建筑,这意味着强风可推动主镜和辅镜移动。但巨型结构的设计必须能保持稳定,不受风力和温度条件的影响,以便光学系统能始终精确地工作。
Solution:
“很简单,我使用MSC Apex的原因就是因为它的集成度——输入几何结构、几何修复、网格划分、分析,然后在集成工具中高水平地进行后期处理,每一步都令人印象深刻。软件使用起来非常方便,效率非常高。” 巨型麦哲伦望远镜的结构工程师Paul Rasmussen说。

MSC Software Helps Giant Magellan Telescope Discover the Universe

Overview:

Where did our universe come from? Since the beginning of time, astronomers and physicists such as Galileo, Copernicus, and Einstein have dedicated their life’s work to this timeless question. Even today, investigating the universe’s origins remains hotly debated. To help answer this, the team at the Giant Magellan Telescope is building a 200 foot-high telescope that will help scientists uncover what has plagued scientists and science fiction enthusiasts alike: Are we alone? How did the first galaxies form? What is the fate of the universe? The GMT is uniquely poised to answer these questions due to its ability to collect more light than other telescopes and to its’ uniquely high resolution (which will be the highest ever achieved in a telescope). The project is sponsored by Astronomy Australia Limited, Carnegie Observatories, Harvard University, and other leading universities and research institutions from around the globe. Due to the complexity of the structure, placement of mirrors, and movements that will occur during operation of the telescope, the engineering team at GMTO used MSC Software’s simulation tool, MSC Apex, to simplify and shorten their design and simulation workflow.

Results Validation:

MSC Apex’s dynamic components for design, specifically its importing utility and meshing features, were instrumental in the design and analysis of the GMT. The software was essential in helping to identify particular wind dynamics issues during the design process, which allowed developers to save time and increase productivity. MSC Apex became a critical tool in the GMT’s design process due to its easy user interface and customized meshing and simulation features. With the aid of MSC Apex, engineers at GMTO will be able to answer some of the toughest questions faced by mankind in a more streamlined, efficient way than ever before.

Adams Simulation Incorporated DOE to Help Design Robot with Human Motion

Overview:

One of the most prominent areas of focus in the robotics industry today is the design of more human-like robots. Giving human features to robots offers tremendous advantages compared to traditional designs; for example, some robots are now designed with human-like legs rather than wheels, which enables them to move more easily in dangerous environments and over obstacles.

Results Validation:

“Prototypes of the ADDAM robot and the robotic arm were built and performed as predicted by the simulation with a high degree of fidelity. The ADDAM robot demonstrated human-like walking capabilities and met all of our other design objectives. The robotic arm can lift an object greater than 5 kg even though its own mass is only 2.2 kg.” - YongKwun Lee, Professor in the Department of Biorobotics in Kyusyu Sangyo University.

Researchers are planning to improve on the design of ADDAM by using multibody simulation to further improve the capabilities of ADDAM, such as by enabling it to perform fast walking, running, jumping, turning, and lifting heavy weights.

Benefits:
  • Adams simulation results achieved good correlation with physical measurements
  • Design of Experiments was applied on the robot model to optimize each design parameter using Adams
  • Prototypes of the ADDAM robot and the robotic arm were built and performed as predicted by the simulation with a high degree of fidelity

Adams仿真帮助诊断膝盖病

Overview:
人类曾经探索过太空、大洋深处,并能回溯过去数百万年的历史。但是,在对人体及其工作方式的认知方面,仍然存在着惊人的大量空白。例如,膝关节处于足底到骨盆的动力学链的中心点。但胫骨与股骨之间的连接所形成的几何约束却微乎其微。需经由大量软组织结构的运作来实现膝关节的稳定性。这些结构的详细工作方式在很大程度上仍是未知的。MSC 的 Adams 是一种多体动力学仿真解决方案,可提供正确的深入分析,有助于更加透彻地了解膝关节的内部运作。
Results Validation:
MAC 研究人员采用 Adams 多体动力学软件来开发最全面、最逼真的膝关节仿真。他们首先为受试者配装标示器。他们利用一个运动捕获系统来记录受试者在实验室内行走、活动时这些标识器的移动。通过核磁共振成像(MRI)技术捕捉骨骼、软骨、半月板及韧带的图像。利用测力板来测量地面接触力、利用 EMG(肌电图)来测量肌肉活动。 然后用采集到的数据来创建每个受试者的各个内部肌骨胳系统的 Adams模型。每个模型由 21 个刚体节段、 53 个旋转关节以及 43 块腿部肌肉组成。定义每个标示器位置的运动约束,并在约束与相应的体节之间放置一个三轴弹簧。这样就能实现刚体骨骼相对于运动约束的移动。将核磁共振成像衍生出的皮肤几何体分为五个刚性体,藉此对足底与地面的接触进行建模。然后定义上述刚体与地面的接触为刚柔接触。 采集这些实验性运动数据能够为模型运动时提供约束下的步态动力学输入。模型受到关节、膝盖处的接触和韧带力以及地面接触力的约束。为确定运动期间的肌力和膝盖荷载进行了一次向前步行的动力学仿真,预测了膝盖组成部分之间的接触力,例如胫骨与半月板之间、胫骨与股骨之间的接触力,以及作用在膝盖韧带上的作用力,例如前十字韧带(ACL)。

Marc Helps Solve Complex Welding Problem to Improve Life of Heat Exchangers

Overview:

Welding is a common practice in the automotive, aerospace, railways, ship building, and machinery industries. It allows for the joining of components by subjecting them to intense localized heat which melts and coalesces the material in the welded region, forming a permanent joint. Multiple process parameters influence the effectiveness of the welding, which include energy source, shape and size of the melt zone, heat affected zone, and speed. Understanding and improving this challenging process through physical iteration can be time consuming and expensive. MSC’s Marc, a nonlinear finite element analysis tool, can provide the required insights needed to solve these parameters in a cost-effective manner.

Results Validation:

The model demonstrated the effects of thermal contact at the joint interface during GTAW welding of the dissimilar materials, and the influence of transverse offsetting of the arc away from the weld line. “We found Marc to be very good in simulating the complex physics of the welding problems. Matching results with experimental data demonstrated that this approach can be used to significant costs by reducing material waste and improving life of the welded parts,” says Singh.

Benefits:
  • Easily try alternative approaches without having to invest in physical experimentation
  • Gain greater insight into temperature gradients with simulation, which are harder to measure in physical tests

Adams Simulations Help Diagnose Knee Problems

Overview:

Mankind has explored the galaxies, the depths of the sea, and looked back millions of years into the past. But, there are still some surprisingly large gaps in our understanding of the human body and how it works. For example, the knee joint is at the center of the kinetic chain running from the foot to the pelvis. But the connection between the tibia and femur provides very little geometric constraint. Knee stability is achieved through the operation of a multitude of soft tissue structures. The details of how these structures work are still largely a mystery. MSC’s Adams, a multibody dynamics simulation solution, can provide the right insights to help get a better understanding of the inner workings of the knee.

Results Validation:

With the use of Adams, MAC researchers have begun to take the steps to grasp the complexity of the menisci function in the knee. They found that increasing the ligament length by about 20% will result in almost a complete loss of force transfer through the menisci during walking. The reduction in the forces absorbed by the menisci increases the forces that were directly transmitted between the tibia and femur, increasing the potential for joint damage and pain. These results will enable researchers and physicians to target and prevent future pain and damage more efficiently than ever before.

Benefits:
  • Predicts ground reaction forces with over 90% correlation to physical results
  • Accurately predicts internal contact forces
  • Determines effect of slack in menisci

Adams Simulation Helps Reduce Need for Physical Testing of Tidal Turbines

Overview:

There are many coastal areas where local geography constrains the movement of ocean tides, resulting in very strong currents. Water is 800 times denser than air so these currents could potentially generate a lot of electricity. GE tidal turbine technology brings proven concepts and industry-leading knowledge to tap into this reliable and predictable energy source. The Oceade* tidal turbine features a buoyant nacelle that enables the turbine to be easily towed to and from the operating site. This eliminates the need for specialist vessels, reducing the cost of installation and maintenance. GE has proven its Oceade* turbine operating at a full 1 Megawatt, injecting over 1.2 GWh of electricity to the grid. This test program has enabled GE to validate the installation and retrieval processes, autonomous running, and the performance and power curve of the new turbine.

Results Validation:

The simulation results provided the information to evaluate the dynamic response of the proposed design prior to investing in a physical prototype and testing. Based on the results, GE design assumptions and margins were verified and opportunities for optimization identified. The company is now moving forward to the testing phase confident that the design has been “de-risked” from a dynamic as well as a kinematic standpoint. “This project was a great working experience that allowed the GE team and MSC consultants to share knowledge and gain experience from their own respective expertise,” concluded Valentin Radigois, Lead Engineer, Mechanical- Components, GE Renewable Energy.

Benefits:
  • Predict the dynamic behavior of the turbine including multiple flexible components
  • Integrate real bearing and gear effect including 3D contacts
  • Simulate various dynamic loads to evaluate complex behaviors and coupling effects
  • Performed modal analysis of the full structure

Automotive Supplier Uses Marc to Improve Design of Stamping Tools

Overview:

Stamping operations used to form metallic automotive components can generate forces of thousands of tons. The tools (die components) that form these products must be able to withstand this cyclic loading environment for the life of the vehicle program. At the same time, it is important to optimize the tool design in order to be competitive. The evolution of higher strength materials also adds to the challenge. The large loads involved in forming these components increase the challenge of designing robust tools. Both linear and non-linear analysis must be used to support the tool design process.

Results Validation:

“In order to get reliable predictions, we prefer to use the nonlinear software Marc to solve these types of problems because it accounts for the inherent nonlinearities of materials experiencing plastic strain,” said Yueming Cheng, Computer Aided Engineering Engineer at Tower International. “In years of using Marc and Mentat, I have found it to be capable of accurately simulating a wide range of nonlinear product behavior under static, dynamic and multi-physics loading scenarios. Marc is also one of the commercial solutions in markets I am aware of that has robust manufacturing simulation capabilities, with the ability to predict general damage, failure and crack propagation.”

Benefits:
  • Accurate simulations help reduce risk of downtime and lost revenues, by predicting regions of potential failure
  • Get the design right the first time with computer models and deliver reliable performance
