【摘要】 汽车遇到正面撞击的几率大约占所有导致死亡的汽车事故的半数,所以对汽车正面碰撞进行模拟计算是十分必要的。由于整个车身结构复杂,发生碰撞时,碰撞过程的作用时间很短,碰撞力和变形特别大,而且是高度非线性的,需运用三维动态显示的非线性有限元软件进行模拟计算。更多还原

【Abstract】 Fifty percent of death accidents happens when the car are crashed in the front. Therefore, the research on the simulation of head - on crash is of much importance. Because of the complexity of the car’ s structure and the shortnessof collision - time, the force is great as well as the distortion. And the response of the structure is of non - linear quality. We apply non - linear methods of finite element analysis to simulate the process of the distortion in 3 - dimention graphs.更多还原
