基于实验设计的行人保护小腿优化
Optimization of Leg Pedestrian Protection Based on Design of Experiments
摘要
Abstract
According to pedestrian protection regulations of our country,a model of leg pedestrian protection for a certain vehicle was established,and the structure optimization measures of adding energy absorbing box and additional bumper were provided.Based on the thickness,the yield strength and their distance to the bumper skin of the absorbing box,the full factorial design of experiments were performed to find the initial optimized scheme.Based on this,the second order response surface model was structured and sequential quadratic programming method was employed to quickly find the structure optimization.Finally,simulation found that the structure optimization obtained by this method shows better results,compared to the initial model and initial optimization combination.关键词
