Presentation by Edan Lazerson, CAE Engineer, Plasan.

The Stormrider is a new vehicle which was designed from scratch and developed by Plasan. Altair Inspire was used for Topology optimization In order to find the ""best"" design for the vehicle front sub frame. The available volume (design space), 5 different load cases and target mass were specified and the optimization software calculated geometry to maximize stiffness. The optimization results were complex to manufacture with traditional technologies; the simulation and design teams collaborated on designing a manufacturable front sub frame assembly. The new design was simulated to ensure it will withstand all the required loads. The front sub frame was implemented and tested on the prototype vehicle. The optimized front sub frame proved mechanically sound, while satisfying the mass and geometrical requirements. The early stage optimization reduced the development time, by creating a valid geometry however, the topology to manufacturable design process is not trivial. In this presentation, we will present the mentioned development stages and compare the test results to the simulation predictions.
