Company:Patrick Air Force Base Products:Adams Industries:Aerospace | 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:

Company:Kosme Products:Adams Industries:Machinery | Kosme - Design and optimization of packaging machines 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.

Company:Meritor Products:MSCOne Industries:Aerospace | MSC One helps Meritor virtually test a new braking algorithm Overview: Regulators are continually increasing the performance standards required of automobile manufacturers. An example is FMVSS 105 and 121 which define the performance of braking systems and are intended to ensure safe braking performance under normal and emergency conditions for heavy trucks and trailers. A typical change in these regulations is to reduce the distance required to stop the truck under emergency conditions. This can be achieved by designing bigger, heavier, more expensive brakes. Ragnar Ledesma, Principal Engineer for Meritor, took a different approach by addressing the algorithms used to control anti-lock braking systems used in nearly all mediumand heavy-duty trucks. Results Validation: The simulation showed the proposed control system brings the vehicle to a complete stop in less than 4 seconds in a stopping distance of 177 feet (54 meters), demonstrating a way to meet the requirements of a tougher regulation without major changes to braking hardware. The results show a nearly constant deceleration response at the driver seat as opposed to the cyclical response with conventional ABS braking. The explanation for the improved performance is explained by the simulation results. The wheel angular velocities and tire slip ratios do not fluctuate from their desired values; hence the new ABS control system can sustain maximum braking forces almost over the entire braking cycle.

Company:Transmisiones y Equipos Mecánicos S.A. de C.V. Products:Adams Industries:Automotive | 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. |  DOWNLOAD |
Company:PROTON Products:Adams Industries:Automotive | 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:
