摘　　要：城市轨道交通车辆转向架用电机的悬挂方式采用架悬式,相比于轴悬式,电机质量从簧下质量成为簧间质量,簧下质量更小,更有利于降低轮轨作用力和改善列车运行品质,利于高速行驶,运行平稳性较好,使得电动机及齿轮副的作用条件大大改善,减小轮轨维护成本。针对架悬式永磁直驱转向架电机悬挂方式,设计并制作了2种试验工装,对架悬式永磁直驱电机分别进行了刚性悬挂安装和弹性悬挂安装模拟,施加电机惯性载荷,采集构架电机安装座关键位置的应力数据进行对比,分析电机的2种架悬方式对转向架构架结构产生的影响,为合理选用及模拟架悬式永磁直驱电机悬挂安装方式提供数据支撑。Frame-suspension mode is used for motors in bogies of urban rail vehicles.In contrast to the axle-suspension mode,the mass of the motor is located between springs,the unsprung mass is small.This configuration is more conducive to reducing the wheel-rail force and enhancing the train’s running quality.It also facilitates high-speed driving and has improved running smoothness,thereby significantly enhancing the working conditions of the motor and gear pair and reducing the maintenance cost of the wheel-rail.Two distinct types of test tooling have been specifically designed and manufactured for the suspension of the motor in the permanent magnet direct-drive bogie.The rigid suspension and elastic suspension mounting modes of the permanent magnet direct-drive motor are simulated respectively,the inertia load is applied,and the stress data of the key position of the mounting base of the frame motor are collected and compared.The influence of the two suspension modes on the bogie frame structure is analyzed,providing data support for the reasonable selection and simulation of the suspension mode of a permanent magnet direct drive motor.
