摆式列车受电弓倾摆机构运动学分析

对于动力分散的摆式电动车组,带受电弓的车体倾摆时,受电弓也要作相应的倾摆,才能保证受电弓与接触网的正常接触。文章根据受电弓技术要求,运用ADAMS软件,对基于四连杆机构的被动式受电弓倾摆机构进行了几何建模以及运动学分析。对倾摆机构尺寸参数进行了优化,使受电弓在车体倾摆过程中始终处于正常工作范围之内,以确保受电弓正常受流,为受电弓倾摆机构的设计开发提供了依据。

Kinematics analysis of pantograph tilting mechanism for tilting train

For power-distributed tilting EMU,in order to make the normal contact between pantograph and cate-nary,it is necessary for pantograph to tilt while EMU tilts.According to the specification of technique of pantograph,this paper uses mechanic dynamics analysis software ADAMS to build geometric model of passive pantograph tilting system based on four-linkage mechanism and uses simulation to analyze on kinematics.Design optimization of tilting mech anism is done to ensure the pantograph working in normal range and the quality of current receiving while the car body tilt.And the result is of practical significance in design of pantograph tilting mechanism.
