Using MSC Apex's "Geometry from Mesh" toolset, DOCAN engineers were able to use the existing FE model instead of starting over completely from scratch.

Utilizing generative design computing to drive future computing power by ensuring high quality and high performance manufacturing

Product design can be purely functional or primarily meet aesthetic criteria. Combining both these approaches, can result in highly functional and yet visually appealing designs.

MSC Apex Generative design and Simufact enable Objectify Technologies to validate the efficient additive manufacturability at the early design stage.

Actran enabled students to study and visualize noise patterns for different natural acoustic board materials and different dimensions, to find the optimum design for equipment enclosure

Under the pressure of joint venture’s MSRP reduction and increasing brand of local automobile enterprise in China, Changan Automobile proposed a 24-month vehicle development cycle to fit the environment. CAE validation almost covers three quarters of the process in the development cycle, which mean the analysis efficiency becomes an urgent issue for CAE department. Both the management efficiency and operation efficiency needs improvement. After multiple communication with excellent suppliers all over the world, Changan decide to build an automatic simulation platform that accelerate CAE process in both operation flow and management flow. Together, Changan and MSC Software implemented ASP project to reach the goal, and cover five current issues which are analysis efficiency, simplifying working flow, gathering scattered CAE data, task management requirement and staff constant improvement.

Using Adams Car, the engineering team at Smedley’s Engineers could precisely determine the manoeuvrability of a heavyweight vehicle.

The British Government challenged the Aerospace & Defence Industry to rapidly develop a modern version of the “iron lung” and develop respiratory ventilators that can help save lives around the world. Marshall Aerospace & Defence Group, located in Cambridge, UK, responded to the challenge and led a taskforce to do exactly that.

Due to the rapid nature of development that was needed, time was not on their side. Marshall’s engineers needed to design, analyze, and manufacture all on almostparallel paths, so that a prototype could be delivered as quickly as possible. As such, the design was rapidly changing, sometimes changing daily, and the engineering simulation team needed to keep up with this rapid pace of development. MSC Apex was able to step up to the challenge and deliver rapid analysis results for Marshall’s engineers, allowing them to develop reliable and safe ventilators and deliver them quickly to save lives.

The simulation using Actran helped to identify weak regions for the hybrid tub and make necessary design modifications to accomplish an equivalent base tire tub.

The Dura Team addressed the issue by carrying out Acoustics simulation using Actran. The team used an open-source Toyota Yaris Trimmed Body FE model to carry out the test.

3D printing has a high potential with its production flexibility and geometry freedom. Yet, it is difficult to be competitive with traditional manufacturing technologies. More economic designs can be created by optimisation but until now this has been a complex process. MSC Apex Generative Design is here to change that.

When designing automobiles, the automotive seal has an important function to play. It seals the interior of the vehicle from the environment. Therefore, it not only needs to be functional, but there needs to some cohesion with the body design of the vehicle. Poor door seal system design can cause water leakage, wind noise, hard opening or closing of doors, and other issues that impair customer satisfaction. Moreover, improper design of the seal can make it difficult to install on the body panel. Therefore, the design rationality and manufacturing process are important for the functionality and performance of the sealing system.

However, the door sealing system comes with several design and manufacturing variables. It is difficult to precisely confirm the individual quantitative effect on the functionalities of these variables at early design stages. Therefore, computer-based simulation of the door sealing system is more practical since it is cost and time-efficient and also helps isolate critical factors.

Digital simulation of rubber sealing is both a complex and scalable problem. This is due to the unique properties of rubber, which is highly nonlinear and nearly incompressible. Besides, sealing simulation also needs to capture contact (self-contact) and geometric non-linearity.

The existing solver was proving to be ineffective since there were several challenges and convergence difficulties.

Vehicle part closures (such as those of doors, bonnet, trunk lid, and tailgate) are overhang sub-assemblies within the vehicle. The main function of these closures is to secure primary access to the vehicle. In addition, they are often required to accomplish diverse requirements over their complete lifetime.

The door closing is a result of complex interactions between different components of the door design, such as the latch, weather seal, etc. Parameters such as energy loss due to an air-binding effect, the inclination of the hinge axis, check-strap, etc. affect the door closure.

The seal has a major effect on the door closing function. For instance, the initial seal must deform as it engages the body panel to avoid defects such as wrinkles and deformation. Given the complexities, it becomes difficult to model the complete system accurately and simulate the door-closing event. With the existing approach, the time required to perform simulation was higher. Also, accuracy is compromised due to approximations.

The design rationality and manufacturing process play an important role in determining the functionality and performance of the door closing system. At early design stages, it is often difficult to precisely confirm the individual quantitative effect of these variables on the functionality. Therefore, computer-based simulation of the door system is more practical since it can isolate critical factors, in addition to being cost effective and time efficient.

The enormous efforts needed to send technical equipment into space require a particularly high degree of lightweight construction. Generative design allows these complex optimisation processes to be significantly simplified and automated. The potential offered by this approach is demonstrated by a case study from German satellite specialist Tesat-Spacecom.

In automotive design, the seat plays an important an important role in ensuring passenger comfort, especially in the case of long-distance drives. Most OEMs today focus on static comfort of seats, while paying limited attention towards dynamic comfort. This project by the students of VIT helped shed some more light on importance of dynamic comfort.

Using simulation tools from Adams, the students designed a model to scrutinize the performance of a semi-active seat suspension system using a PID controller and a newly designed magneto-rheological fluid damper. The software helped the students to test their model seamlessly and cost effectively on real time basis, using virtual prototyping and virtual testing, before physical prototyping and testing.
