参考国内外有关地铁、轻轨车辆耐碰撞设计规范及准则,利用Hypermesh和LS-DYNA有限元软件模拟了一列车以20 km/h的速度正面碰撞另一列相同的静止列车的碰撞过程。仿真模型中模拟了钩缓装置的力学特性以及车钩的失效和脱落现象。从乘客生存空间、纵向平均加速度等方面评价列车的耐撞性。研究结果表明,该型地铁列车的耐撞性能满足相关标准的要求。 Reference to the domestic and foreign relevant subway and light rail vehicle collision design specifications and guidelines, using Hypermesh and LS-DYNA finite element software to simulate a train at 20 km / h frontal collision another column of the same static train collision process. The simulation model simulates the mechanical properties of the hook and loop device as well as the coupler’s failure and shedding. Evaluating the crashworthiness of trains from the aspects of passenger’s living space and longitudinal average acceleration. The results show that the crashworthiness of this type of subway train meets the requirements of relevant standards.
