为了提高车辆的被动安全性,需提高车辆前端结构的防撞能力,城轨车辆需满足2列空载列车相对速度25 km/h的碰撞要求.主要阐述如何合理配置车辆钩缓装置中的前3级吸能结构能量,并通过ISIGHT软件,优化第4级吸能结构,即头车前端底架的碰撞吸能区,使车辆4级吸能结构能够合理有序变形,吸收更多能量.

@@@@In order to improve the passive safety of vehicles, increase of impact resistance of structure of the front end of vehicle is needed. Urban rail vehicles must meet the collision requirements of relative speed of the two no-load train at 25 km/h. The paper mainly describes reasonable device configuration for the first three level energy absorbing structures in the vehicle coupler draft gear. With ISIGHT software, fourth level energy absorbing structure is optimized, namely at crash area of the front chassis, and the vehicle with four level energy absorbing structure can reasonably and orderly deform to absorb much more energy.
