SHAPE OPTIMIZATION FOR HEAD AND KNEE IMPACT FEATURING ADAPTIVE MESH TOPOLOGY AND A DISCRETE VARIABLE
A successive linear response surface method (SRSM) is applied to the shape optimization of vehicle crashworthiness problems involving knee and head impact. A preprocessor is used to parameterize the geometric model and mesh topology. An upper limit on the element size is used as a criterion for the mesh adaptivity. Simulation is conducted using the explicit dynamic analysis method. The study demonstrates the effectiveness of adaptive meshing and simulation-based shape optimization in problems of complex behavior such as crash simulation.
