矿车碰撞过程的建模与仿真分析

Modeling and simulation of the collision course of tramcar

将碰撞过程视为一种特殊的振动过程 ,以伯努利—欧拉梁为力学模型 ,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 ,分析了不同速度、不同质量的矿车与刚性车挡之间碰撞力的变化规律。

The collision course is regarded as the vibration course. The Bernoulli-Euler Beam is established as the mechanical model of the car bumper. The collision course between the tramcar and the car bumper is simulated based on the simulative software Simulink the component of MATLAB. The conclusions of the relationship between the max collision force and the mass or the velocity of the tramcar are drowned from the simulation above.
