低速磁浮车动力学建模及平行四边形机构分析

车辆结构设计必须满足动力学要求。对于低速磁浮列车而言,车辆与线路之间的运动解耦功能主要由车辆的二系悬挂实现。二系悬挂包括固定滑台、自由滑台、空气弹簧和平行四边形机构等,其运动同时受线路和刚性车厢的限制。文章先分析了在曲线上,平行四边形机构对车辆横向力分布的影响,然后利用多刚体动力学建模方法建立低速磁浮列车的动力学模型,并进一步阐述平行四边形机构在曲线通过中的重要作用,分析曲线通过时二系悬挂各构件的运动情况。

Dynamics modeling of low-speed maglev train and analysis of the parallelogram mechanism

The structural design of the vehicle should conform to the rules of dynamics.For low-speed maglev train,the motion decoupling function between the vehicle and railway is mainly achieved by the secondary suspension system.The secondary suspension system consists of fixed slipway,free slipway,air springs,parallelogram mechanism,etc.And its movement is restricted by both the railway and rigid vehicle body.This paper first analyzes the effects of parallelogram mechanism on the distribution of vehicle's horizont...
