    Patrick AFB

    Overview:
    Ejection seats must work perfectly every time they are used in an enormously wide range of altitudes, aircraft motion profiles, wind conditions and pilot weights while at the same time taking manufacturing variation into account. Physical testing of course plays a pivotal role in ejection seat design but time, cost and safety limit the number of situations that can be tested to far fewer than the number of potential ejection scenarios. Analysts at the Naval Surface Warfare Center (NSWC) at Indian Head, Maryland, and the 45th Space Wing at Patrick Air Force Base, Florida, have developed a model of an ejection seat using MSC Adams rigid body simulation software. During the model’s initial 5-year joint-force development process, Adams was the first professional dynamics software used to completely model the complex physics involved in the deployment of an ejection seat.
    Challenge:
    Improve ejection performance and safety.
    Solution:
    Adams was used to model the complex physics involved in the deployment of an ejection seat.
    Benefits:
    • Accurate Simulation
    • Reliable Analysis
    • Improved Design Process

    Overview:
    Kosme produces a full range of turnkey filling, labeling, capping, packaging and conveying solutions for beverage products including soft drinks, water, beer, wine, and spirits, as well as personal care products.
    Challenge:
    In developing custom solutions for customers, Kosme is frequently asked to develop machines that will operate faster and more reliably than their predecessors. Increasing the speed of machines raises inertial loads, creating the potential for vibration and resonances that could substantially reduce the life of the machines and cause breakdowns. In the past, Kosme engineers used hand calculations to estimate the performance of components and built physical prototypes to evaluate system performance. Problems were frequently discovered during the prototype stage. These problems often required many iterations of revisiting the design and modifying and re-testing the prototype.
    Solution:
    MSC Nastran and Adams simulation software made it possible for Kosme to design, optimize and visualize packaging machines prior to the prototype stage. The result is that the company is able to engineer substantial performance improvements while getting the design right the first time.
    Benefits:
    Simulation makes it possible for Kosme to design, optimize and visualize packaging machines prior to the prototype stage. The result is that the company is able to engineer substantial performance improvements while getting the design right the first time.
    • Increase the processing speed of bottling machines by 50%
    • Reduction of vibration levels
    • Reduction of mass of critical moving components by 20% to 30% while reducing stress levels.

      Transmisiones y Equipos Mecánicos S.A. de C.V.

      Overview:
      Joel Ortiz is a Concept Engineer at Transmisiones y Equipos Mecánicos S.A. de C.V. (TREMEC) in Querétaro, Mexico. TREMEC is a leading producer of rear wheel drive light duty manual transmissions. Ortiz and other TREMEC engineers are responsible for ensuring that the performance of TREMEC transmissions matches up to demanding customer expectations. In the past, the only method available to resolve performance issues in prototypes was to go through the time-consuming and expensive process of making modifications to the prototype and hoping for the best.
      Challenge:
      In testing an early prototype of a six-speed manual transmission, jumps were seen in the force applied to the shifter lever and felt by the driver of the vehicle. These jumps in shifting effort, called nibble by transmission manufacturers, do not affect the performance or durability of the transmission, but they are important because the reaction force against the gear shift helps define the shift quality of the transmission for the driver.
      Solution:
      Ortiz created a virtual prototype of synchronization mechanism in Adams with 17 parts including the shift rail, fork, roller detent, gear synchronizer cone, inner synchronizer ring, blocker ring, strut, sleeve, intermediate ring, clutches and gears. The geometries of these parts were based on the measurements of the prototype transmission.
      Benefits:
      Ortiz used a virtual prototype to reduce nibble by 93% from the early prototype to the production model, contributing to rave reviews from automotive journalists.

      PROTON - Driving Engineering Innovation

      Overview:
      PROTON develops mechanical and structural components, sub systems and complete vehicle systems.
      Challenge:
      In developing complex mechanical and structural automotive components, going through multiple build-and-test hardware prototype cycles to verify performance, stress and fatigue life is just too timeconsuming and expensive. This issue can be addressed by evaluating and refining designs with analysis tools up front in development, reducing test cycles later in the development process. PROTON’s pioneering spirit naturally has led Mr ismail to not just stop at traditional methodologies in computer-aided engineering for design analysis. As the risk of failure in any design was becoming more and more significant and he was constantly looking at areas to assess risk parameters and minimize any risk factors, he needed to turn to industry-leading simulation analysis tools that would be able to provide him with the necessary accurate foundation to progress his methodology. Mr. Ismail realized that conventional virtual development approaches are no longer sufficient to meet the increasing standards of accuracy required at PROTON. Conventional approaches do not take into consideration the variations that affect finite element analyses. Mr. Ismail needed proven tools that produced the most accurate results, allowing him to capture the potential failures and provide the nature of failures so that these can be mitigated in the process. With resource efficiency on his mind, Ms Ismail also needed to manage test accuracy while reducing the dependency on running too many variations.
      Solution:
      With MSC, Mr. Ismail was able to conduct multi- run design improvement studies which can be used to assess design sensitivity to product and environment variability, discover unknown design variable interactions, and provide a global view of the overall design space.
      Benefits:
      • Visible quantification of design risk or reliability
      • Identifies areas of high risk in a design
      • Provides the ability to modify design variables relative to reliability
      • Provides a means to compare differing designs

      Triple Eight Race Engineering Ltd. - Racing to Win

      Overview:
      Graham Lawrence is a Race Engineer for Triple Eight Race Engineering Ltd. in Greatworth, Banbury, Oxfordshire, United Kingdom. Triple Eight Race Engineering designs, builds and races Vauxhalls on behalf of the UK arm of General Motors (GM). Lawrence and his team are responsible for designing cars that race in the British touring Car Championship (BTCC). In the past, very little simulation was performed. Instead, components were physically manufactured and run on race cars during costly test sessions to evaluate their reliability and optimize their design.
      Challenge:
      2007 saw the start of a new era for the BTCC as the series adopted the S2000 regulations that are used in the World Touring Car Championship. The changes in regulations meant that Triple Eight’s Vauxhall Astra Sport Hatch had to be replaced by a Vauxhall Vectra. Lawrence and his team were faced with the challenge of designing a new vehicle to meet unfamiliar regulations from the ground up. There was no time to field a competitive vehicle using traditional build-and-test methods.
      Solution:
      Patran pre/post-processor and MD Nastran multidiscipline simulation software.
      Benefits:
      Despite limited development time the new Vauxhall Vectra proved an almost instantaneous success, winning its second race and winning both the driver and manufacturer’s title in 2007. 2008 was even more successful for the new car as it won all three championship titles: driver, manufacturer and team.

      Agency for Defense Development - Improving the Survivability of Airframes

      Overview:
      Jong H. Kim is Senior Engineer for the Agency for Defense Development (ADD) in Daejeon, South Korea. Kim and other members of the Aircraft Structural Team are responsible for, among other things, improving the survivability of airframes so that aircraft will be able to return to base after being hit by enemy fire. The primary method of assessing design alternatives in the past, live fire testing, is so expensive and time consuming that aircraft could not be tested for all of the likely damage scenarios.
      Challenge:
      ADD needs to evaluate various wing fuel tank designs for their ability to withstand a high velocity projectile impact. Their goal is to predict and quantity the damage from impact so that subsequent survivability analysis, such as residual strength and structural/flutter stiffness can be performed on the remaining structure. This also provides understanding of how the aircraft should be flown to enable it to safely return to base. In order to accomplish these objectives, it is necessary to simulate the very complex phenomena of hydrodynamic ram which occurs when a projectile impacts a structure containing fluid and penetrates it or detonates near it to produce a blast wave.
      Solution:
      Patran, MSC Nastran, Flightloads, and Dytran finite element analysis software
      Benefits:
      ADD has demonstrated the ability to simulate the damage to the airframe caused by the penetration and detonation of a projectile. This is expected to reduce the amount of live fire testing required and to make it possible to evaluate the effect of far more damage scenarios.

      TI Automotive - Focus on design simulation

      Overview:
      When leadership at TI Automotive—a global supplier of fuel storage and delivery systems for cars and trucks— evaluated the company’s product development process, it discovered repeated design and test cycles. MSC gave the engineers at TI Automotive the essential tools they need to save time and money, by reducing prototyping.
      Challenge:
      The problem that TI faced was that simulation was disconnected from the design process. Compounding the situation was that in going from CAD geometry to simulation models, many data translations or fixes were necessary. TI really only had one simulation expert in the company, which kept analysis from being scaled across the enterprise.
      Solution:
      Using design simulation to support its product development process would enabled TI to account for complexities of manufacturing upfront, and, additionally, would move simulation from the desktop of one expert engineer to that of many engineers.
      Benefits:
      Since TI implemented an engineering simulation solution from MSC Software, the supplier of enterprise simulation solutions. The benefits have been significant.
      • TI Automotive now is able to run virtual tests without having to rely on the one in-house expert, which eliminates the previous bottleneck.
      • TI reduced physical prototyping, and analysis time went from two weeks to four days per design. With less than a half hour of user effort, engineers are able to create a new design, run all of the simulations, and receive results.
      • The new simulation capabilities have driven notable enterprise savings.
      • The use of simulation has aslo brought gains to the top line, by demonstrating significant engineering expertise and competitiveness to end customers early in the sales cycle.
