摘要
行人保护仿真分析精度是直接影响到C-NCAP(2018年版)最后得分的重要数值。文章基于CAE技术,对某车型发动机罩特征区域进行行人保护头部冲击仿真分析,并与试验结果进行对比分析。得出仿真和试验的头部加速度曲线基本一致,且80%试验点头部伤害值误差均小于10%,满足仿真分析精度要求。由此可推断,该行人保护模型可用于后续结构开发与优化分析。
The accuracy of pedestrian protection simulation analysis is an important value that directly affects the final score of C-NCAP(2018 version).Based on CAE technology,this paper analyzes the head impact simulation for pedestrian protection in the characteristic area of the engine hood of a certain vehicle,and compares it with the test results.The results show that the head acceleration curves of simulation and test are basically the same,and the head injury criteria error of 80%test points is less than 10%,which meets the accuracy requirements of simulation analysis.It can be concluded that the pedestrian protection model can be used for the subsequent structural development and optimization analysis.
