车辆正面碰撞与小角度碰撞仿真模拟研究

摘要

主要研究了车辆正面全宽碰撞和小角度碰撞,分析2种形式下车身的位移变化.首先利用HYPERMESH软件对模型进行参数设置,设置初始速度均为56 km/h,然后利用LS-DYNA对模型进行碰撞分析,最后利用HYPERVIEW对结果进行分析查看并得出结论:当整车以56 km/h的速度撞向刚性墙面时,小角度碰撞对驾驶员生存空间影响更大.%This research is mainly designed for the study of the full frontal collision and the small angle collision, and then it makes an analysis of the vehicle body's displacement changes under the two forms.Firstly, it sets the model parameter of initial velocity to 56 km/h using the software of HYPERMESH.Secondly, it uses LS-DYNA to simulate the collision.At last, it analyzes the result using HYPERVIEW and it comes to the conclusion that when the vehicle crashed into a rigid wall at the speed of 56 km/h, the small angle collision has a greater impact on the driver's survival space.
