摘要
文章通过计算机仿真分析,研究车内乘员在某轿车翻滚碰撞过程中的损伤,运用Hyper Mesh建立整车及试验平台车的有限元模型,所使用的假人模型来自VPG(虚拟实验场技术)软件中自带的非商业假人可变形50百分位假人模型,采用显示有限元分析软件LS-DYNA进行求解,得到整车在车辆翻滚碰撞过程中乘员的运动状态,提取乘员各主要部位的损伤值,分析乘员的损伤原因,为乘员的保护提供依据。
This article researches on occupant injury in a car rollover crash by computer simulation. Establishes a finite element model of the vehicle and a domestic car by Hyper Mesh.The dummy in this article comes from VPG（virtual practice ground）, the non-commercial deformable 50%.LS-DYNA is explicit finite analysis software, it calculates the crash model, gets motion state of the vehicle and occupant during rollover crash; extracts the major parts of occupant injury values, analyzes the reasons for occupant injury, provides the basis for the occupant protection.
