Design of Steerable Crash Pad Based on Lightweight&Multi-Objective Robustness
To reduce the cost of the crash pad and improve the robustness of the system,the topology optimization is used to obtain the optimal force transmission path of the energy absorption unit of the crash pad under multiple working conditions,and the factors that have the greatest impact on the performance of the crash pad are obtained through single factor analysis.Then,the robust design based on Taguchi Method is carried out,and the multi-condition problem is regarded as a multi-objective optimization problem to obtain the optimal parameter size.Finally,the simulation verification is carried out and compared with that before optimization:after optimization,the satisfaction is increased by 21%,and the length is reduced by 1/5 compared with the same type of TS grade crash pad.The research provides a rigorous theoretical basis for topology optimization based on hybrid cellular automata method in the initial shape design of the crash pad,and the design method plays a guiding role in dealing with the compromise and simplification of the complex problem of the crash pad under multiple working conditions.
