| 摘 要： | 分析了汽车碰撞有限元法的基本理论和非线性有限元理论,通过对接近速度的改变对车身碰撞减速度的影响,和不同接近速度下两车碰撞吸收能量特性的分析,得出了在不同的接近速度下碰撞时,随着接近速度的增加,车身碰撞瞬时减速度增加,且增幅较大;两车迎面相撞时,大车吸收的能量小于中型车吸收的能量等结论。

| Abstract: | The finite element method and the non-linear finite element theory on automobile crash is analyzed,through the influence analysis of the change of approach speed to the automobile body crash deceleration and the characteristic(analysis) of energy absorbed by two vehicles under different approach speeds,the conclusions have been obtained that the(automobile) body crash deceleration speed increases with the approach speed,and the increasing range is large;When two(vehicles) front surfaces bump into eachother,the absorbed energy of large vehicle is smaller than that of the standard size(vehicle.) |
