GCY470型调车机车侧面碰撞仿真分析

1、    gcy470型调车机车侧面碰撞仿真分析    赵德宇 田茂鹏摘 要 为研究地铁调车机车在侧面碰撞情况下的碰撞响应，建立了调车机车碰撞的有限元模型，按照不同工况，对其在道岔上发生不同部位的侧面碰撞进行仿真分析。结果表明，在碰撞过程中调车机车的轮对抬升量已超过车轮的轮缘高度，机车存在极大的脱轨风险。同时，在侧面碰撞中机车车体的吸能能力有限，无法耗散太多的碰撞能量。为提高机车在侧面碰撞中的吸能能力，在相关车体设计和优化时，可参考传统轨道车辆的纵向多级缓冲吸能系统进行设计，吸收碰撞能量，减少碰撞造成的损害。关键词 调车机车;

3、the collision response of a subway shunting locomotive in the case of a side collision， a finite element model of the shunting locomotive collision was established. according to different working conditions， the side collisions at different locations on the turnout were simulated and analyzed. the r

4、esults show that the vertical rising amount of wheelsets of the locomotive has exceeded the height of the rim of the wheel during the collision， and the locomotive has a great risk of derailment. at the same time， the locomotive bodys energy absorption capacity is limited in a side collision and can

5、not dissipate much collision energy. in order to improve the energy absorption capacity of a locomotive in a side collision， reference may be made to the longitudinal multi-stage buffer energy absorption system of a traditional rail vehicle to design the side multi-stage buffer energy absorption system when designing and optimizing the relevant car body to absorb the collision energy and reduce the damage caused by the collision.keywords： shunti
