摘要
针对列车碰撞过程中两车之间的运动状态,设置了车钩连接和分离两大状态,将碰撞过程中钩缓系统的运动细化为弹性压缩、塑形压缩、弹性伸长和车钩力为0的4个子状态,运用simulink/stateflow建立仿真模型。基于此,建立了两列单节车碰撞的Matlab/simulink仿真模型,观察其在不同撞击速度下的缓冲器特性。分析结果表明,所建立的车钩缓冲器模型能够较好地反映车辆碰撞过程中车钩的实际状态。
According to the process of train collision and the state between two vehicles, it sets up two major states of the coupling and separation. It divides the collision process into four states： elastic compression, compression, elastic elongation and 4 substates of 0 coupler force. It also establishes the simulation model by using simulink/ stateflow. Based on this, a simulation model of two list car collision is builtup for observing buffer characeeristies at different impact velocities. The analysis results show that, coupler buffer model established in this paper can better reflect the actual state of the coupler in the process of vehicle collision.
