利用简化的列车二维碰撞模型,建立列车碰撞运动微分方程,采用数值积分方法,以20节车厢连挂列车平面刚体模型为对象,对列车在各工况下受碰后的动力学行为进行研究,得到了整列车受碰后的最大车钩压力、最大接近线速度、角速度等动态性能参数。在此基础上,对车钩压力随运行时间的变化情况、各节车的最大车钩压力、最大接近线速度、角速度进行了分析和探讨,结果表明:利用该仿真分析方法研究列车受碰后的动力学行为是有效的。
Using the simplified two-dimensional collision model of train, the differential motion of train collision was established. The numerical integral method was used to study the dynamic behavior of the train under various conditions after being touched by the planar rigid body model of 20-car train. , Get the whole train after the collision of the maximum coupler pressure, the maximum line speed, angular velocity and other dynamic performance parameters. On this basis, the change of the coupler pressure with the running time, the maximum coupler pressure, the maximum approaching linear velocity and the angular velocity are analyzed and discussed. The results show that the simulation analysis method is used to study the dynamic force Learning behavior is effective.
