摘要:
为了提高某保险杠系统的耐撞性,该文提出了一种优化设计方法。根据具有旋转性的二次回归组合试验设计方案选取设计点,在这些设计点处利用有限元法获取试验数据。然后运用最小二乘法建立刚性板最大位移、撞击力峰值和总质量的高精度响应面。综合考虑零件厚度的变化范围、安全性和轻量化要求,运用序列二次规划法对建立的响应面进行求解计算,得到一组最优值。结果显示仅需17次计算,误差均在5%以内。
Abstract:
In order to improve the crashworthiness of a bumper system,an optimization design method is proposed here.Design points are selected according to an experimental design scheme with rotatable quadratic regression composition,and experimental data are obtained from these selected design points by using the least square method.The high-accuracy response surfaces of the rigid plates'maximum displacement,crash peak forces and total masses are built by using the finite element method.Taking the range of components'thickness,safety and requirement of light weight into consideration,the sequential quadratic programming method is used to optimize these response surfaces,producing a group of optimal values.The results show that only 17 runs are needed and the relative error is within 5%.
