Auburn University Applies HyperWorks to Optimize the Design of Composite Suspension Components and Monocoque for a SAE Formula Student Racecar

More specifically, for the monocoque suspension mass optimization, CAD geometry was initially imported into HyperMesh and a meshed model was created. After assigning composite material properties to the primary monocoque structure and aluminum properties to the bonded end cap, design and non-design regions of the model were specified. Loads were also input, and the maximum monocoque displacement was constrained to a maximum allowed value. A three-step OptiStruct optimization process for composite structures was then applied to minimize the monocoque volume. After analyzing the optimized results in HyperView, the team created a manufacturable geometry, which was subsequently evaluated using linear finite element analysis to ensure that all design requirements were met.
