轨道车辆防全向错位前面板防爬器性能仿真

Simulation of rail vehicle anti-climber with anti-omnidirectional displacement front panel

运用LS-DYNA对一种新型防全向错位前面板防爬器抑制横向滑移和垂向爬升的能力进行仿真,通过模拟2节编组列车车辆间水平初始偏转为2°和3°的碰撞工况,分析比较传统前面板防爬器和新型防全向错位前面板防爬器对横向运动的抑制能力。在此基础上,仿真分析车辆间初始垂向偏移分别为20和40 mm的碰撞工况,检验新型防爬器的垂向防爬能力。仿真结果表明,在碰撞工况下,新型防全向错位前面板防爬器的横向运动和垂向运动抑制能力均优于传统面板防爬器,可在车辆设计中推广使用。

The lateral and vertical motion restraining ability of a new type of anti-climber with anti-omnidirectional displacement front panel is simulated in LS-DYNA.The collision conditions with initial deflection of horizontal 2°and 3°between 2-vehicle trains are simulated,and the lateral motion restraining ability between the traditional front panel anti-climber and the new one are analyzed and compared.On this basis,the collision conditions with initial vertical deflection of 20 mm and 40 mm are simulated and analyzed to test the vertical motion restraining ability of the new anti-climber.The simulation results show that,under the collision conditions,the lateral and vertical motion restraining ability of the new type anti-climber with anti-omnidirectional displacement front panel is better than that of the traditional one,and it can be widely used in vehicle design.
