Crashworthiness design is an important and challenging problem for vehicle designers.The performance of vehicle in a collision event has a direct impact on the safety of drivers, passengers and pedestrians.The difficulty of crashworthiness analysis is widely recognized, because it involves highly nonlinear and dynamic effects of the vehicle structure, such as large deformation, large strain, material nonlinearity, contact and non-linear wave propagation, and even structural and material damage.Due to the high cost of crashworthiness analysis, research work on the computational efficiency attracts great attention.The present paper applies the inertia relief method together with HCA (hybrid cellular automata), which is one of heuristic structural topology optimization approaches, to crashworthiness topology optimum design.A model car is developed and tested.
