When developing the sub-systems of a vehicle, compromises have to be made among several contrasting objectives. On one hand, one wants to set all sub-systems – such as suspensions – so that they allow efficient and safe handling of the vehicle. On the other hand, comfort cannot be sacrificed too much. Being the support of the vehicle and providing forces necessary to control it, pneumatic tires are one of the most important components. However, it is very challenging to model them due to both their complicated composition and the materials used in their manufacturing process. On top of that, the modeling is done by suppliers and an in depth understanding of the interaction with the vehicle must be attained.

The James Webb Space Telescope is a highly sensitive instrument that is positioned using a precise optical metering support structure. This supporting structure is made from composites to reduce thermal expansion effects while reducing weight. The instrument and structure are subjected to temperatures ranging from ambient during launch to cryogenic temperatures while in orbit. Dynamic and static loads are encountered during launch and in operation respectively.

Sporadic use of advanced finite element analysis (FEA) software, such as nonlinear analysis by design engineers, can result in either excessive refresher training time or a bottleneck while in the queue for an analyst. The cause is a result of different types of solvers requiring different models. Commercially available translators can help, but still require significant amounts of cleanup. However, by integrating solvers in MSC Nastran’s SOL 600, the same model in the familiar MSC Nastran format can be used for both liner and MSC Marc nonlinear analysis.

The use of glass in the exterior facades provides more light and good ambience to the inhabitants of a building. In our case, this leads to a high increase of the use of glass in the facades. The curtain wall is formed by an aluminum framework with steel connections. These steel connections are welded to the building while steel beams and bolted to the aluminum frame.

In the agricultural and heavy machinery industries, durability and strength are some of the most important indicators of quality. Maintaining high levels in these areas requires the application of many different tests and assessments to the end product. However, one of the most time-consuming parts of the production is the lengthy process of building physical prototypes, testing them for durability, then redesigning several parts and starting all over again. This process can significantly extend the time it takes to get a product to market. This was the case for John Deere Welland Works while developing a 20-foot rotary cutter system.

Rhodia Engineering Plastics is one of the largest suppliers for polyamide engineering plastics. They faced challenges in supporting their customers in the design of polyamide parts, taking into account the influence of fiber orientation for reinforced polyamide material, and providing the best material data possible to support simulation technologies.   SOLUTION • Calibration of a …
