基于ADAMS的列车门系统承载传动机构动力学仿真研究

Research on Dynamic Simulation of Load-Bearing Transmission Mechanism of Train Door System Based on ADAMS

为了解决列车门系统承载传动机构的磨损、润滑不良及扭簧变形等问题,本文基于ADAMS仿真软件,通过对门系统承载传动机构工作原理的分析,确定目标函数和约束条件,实现对该机构的动力学仿真,并综合考虑滚销与丝杠的接触刚度、摩擦系数及扭簧初始角度对门系统的影响规律。结果表明,接触刚度的增加使前后滚销受力都增加;摩擦系数的增加使电机的输出扭矩增加;扭簧初始角度的增加使前滚销受力减小、后滚销受力增加。该仿真分析能够为后续列车门系统的维修检测提供一定参考。

In order to solve the problems of wear,poor lubrication and torsion spring deformation of the load-bearing transmission mechanism of the train door system,based on ADAMS simulation software,through the analysis of the working principle of the load-bearing transmission mechanism of the door system,the objective function and con⁃straint conditions were determined to realize the dynamics of the mechanism simulation in this paper,and the influ⁃ence of the contact stiffness,friction coefficient and the initial angle of the torsion spring on the door system were comprehensively considered.The results show that the increase in contact stiffness increases the force on the front and rear roller pins;the increase in friction coefficient increases the output torque of the motor;the increase in the ini⁃tial angle of the torsion spring reduces the force on the front roller pin and the force on the rear roller pin.The simula⁃tion analysis can provide a certain reference for the subsequent maintenance and testing of the train door system.
