矿车碰撞过程的单自由度模型仿真

Single degree-of-freedom model and simulation of tramcar collision course

以单自由度弹簧—质量系统为力学模型,以MATLAB的组件Simulink为仿真工具,对矿车与刚性车挡的碰撞过程进行动态模拟。根据仿真结果,分析了矿车与刚性车挡之间的碰撞力及碰撞时间的变化规律,从而得到了最大碰撞力与矿车质量及矿车速度之间的回归公式,为刚性车挡的设计提供了主要参数。

Single degree-of-freedom spring-mass model of tramcar and car bumper collision course is built and dynamic simulation is conducted by MATLAB component Simulink.The law of collision force varying with collision time is discussed and the formula for calculating the maximum collision force,which is a main parameter required in the dumper design,is obtained.
