摘要:
为了研究汽车正面碰撞时副仪表板对乘员损伤的影响,本文以三维建模软件CATIA和仿真软件HYPERMESH和DYNA为主要研究工具,确定碰撞区域、碰撞点和实验方法,建立碰撞有限元模型。通过对碰撞吸能曲线的分析,找出影响碰撞吸能的关键因素,并对关键因素进行优化,优化后的模拟结果为60 g,实物试验得到的结果是58.335 g,模拟值与试验值接近,验证了优化模型的有效性。In order to study the injury of passengers effected by floor console in frontal collision, with 3D model soft-ware CATIA and finite model software HYPERMESH and DYNA, the contact area, impact points and test method are defined and collision finite model is established. By analyzing energy absorption curve, the key factors are found and optimized. The analyzing result is 60 g, which is similar with the testing result 58.335 g. The experiment verifies the effectiveness of the optimization model.
