Experimental Study and Optimization on Crashworthiness Performance of a Car Door Trim System

  • 摘要: 应用试验方法和有限元法对车门内饰板总成的侧面耐撞性进行研究,并在此基础上优化缓冲块的结构设计,以获得更高的吸能特性。参照国家标准和行业规范,确定门内饰板总成胸部、腹部及胯部的碰撞区域,设计、制造冲击头,并在摆锤试验台上对其进行耐撞性测试;基于LS-DYNA平台,建立门内饰板总成的有限元模型,其中材料模型中主要参数均通过实验直接获取,基于建立的有限元模型进行耐撞性分析,模拟结果和试验结果符合较好;以建立的有限元模型为基础,基于实验设计和支持向量机方法建立缓冲块吸能特性的替代模型,并以此为基础对缓冲块进行结构优化。优化后缓冲块吸能增加86.0%,门内饰板总成吸能增加42.2%。
