转臂式城轨车辆转向架径向机构运动学分析

摘要

In this paper,the radial mechanism of bogie of a metro vehicle based on the position of the wheel to arm was designed.The radial function of mechanism was theoretically calculated,and the kinematic performance through curve was simulated in ADAMS/View.The results of simulation and the comparisons to theoretical analysis show that the radial bogie meets the requirements of the curve negotiation,and the designed radial mechanism is reasonably and has a certain radial function.%基于某型号地铁车辆转臂式转向架进行了径向机构的设计,对径向机构的径向功能进行理论计算,并利用ADAMS/View运动学仿真软件对径向转向架通过曲线时进行运动学仿真.通过分析仿真结果及其与理论计算值的对比,表明该径向转向架满足曲线通过要求,径向机构设计合理且能实现径向转向功能.
