机械连接销磨损状态下汽车列车侧倾动态仿真

Dynamic Simulation of Combination Vehicle Rollover in the Case of Worn Mechanical Coupling Pin

建立了汽车列车侧倾过程的数学模型,研究了在汽车列车连接销磨损状态下发生侧倾时的一些重要特性;并利用MATLAB和VEH-SIM的联合计算机仿真,比较了不同车况下车辆的转向稳定性,重点讨论了在连接销磨损工况下汽车列车转向时的侧倾情况,探讨了实现汽车列车安全稳定性能的途径。

A mathematical model of the process of the rollover of combination vehicle was established,and some important characteristics in the process of rollover in the case that the connecting pin of combination vehicle had been worn were analyzed and researched. Vehicle steering stability under different conditions was analyzed and compared by the computer simulation of MATLAB and VEH-SIM,focusing on the conditions that the connecting pin was worn in combination vehicle steering roll situation. Finally,the way of realizing the safe and stable performance of combination vehicles was explored.
