FEA is another key engineering support area that DSM offers that makes it
possible to answer many questions before prototype parts are made. Linear,
non-linear, as well as modal analyses are common analyses performed for
automotive customers. Any of these analyses are commonly used to validate new
designs as well as troubleshoot current designs.
DSM uses Abaqus®, LS-Dyna® and OptiStruct®, which are mainstream FEA software
codes offering a variety of capabilities. Each has its own unique advantages
including structural optimization of mechanical structures however, OptiStruct
is an obvious favorite for developing quick and robust concepts and for
improvements throughout the entire design phase.
DSM has been using Altair OptiStruct® software for nearly 10 years. Components
that have been optimized include accelerator pedals and brackets, manifolds,
covers and shrouds, tension supports and guides, fans, electrical/electronic
enclosures, office chairs, hand truck frames, wheel chair wheels and seats,
gears, and many metal replacement projects.
