A crashworthiness simulation model was established first and topology optimization was conducted based on hybrid cellular automata (HCA). The material distribution from topology optimization was used to generate H-shaped cross-section. Base on the Kriging modeling technique, size optimization was executed to acquire the optimal sectional dimension. The final result demonstrates that the proposed method is able to provide a reasonable cross-sectional shape and size of the bumper, and to improve the crashworthiness of the bumper beam and to achieve a lightweight design.
