【摘要】 综合运用mode FRONTIER和MADYMO软件,以上海汽车集团公司自主研发车型为研究对象,对腿部碰撞区域的接触刚度进行了优化设计,在满足2003/102/EC第一阶段法规要求的前提下,获得了腿部碰撞区域所需的最小变形空间;结合有限元仿真分析评估该车型的行人腿部保护性能,并对车身设计进行了改进。仿真结果表明,改进后的车身能够满足2003/102/EC第一阶段法规的相关要求。更多还原

【Abstract】 Based on a car developed by SAIC,the optimization design of contact stiffness of pedestrian leg impact areas was carried out with the software mode FRONTIER and MADYMO,and the minimum deformation space required for leg impact areas under the prerequisite of meeting the requirement of 2003/102/EC Directive Phase I was also gotten;combined with FE simulation and analysis,pedestrian leg protection performance was assessed and the modified design of cab was carried out.The results showed that the modified body could meet the requirements of 2003/102/EC Directive Phase I.更多还原
