| 摘 要： | 分析了低速磁浮列车结构及其运动学关系,利用多刚体动力学建模方法,建立了低速磁浮列车的动力学模型,分析了曲线通过时二系悬挂各构件的运动情况,阐述了平行四边形机构在曲线通过中的重要作用.仿真结果表明:二系悬挂系的平行四边形机构把横向力较平均地分配到各个模块上,使得各个模块沿着曲线达到合理分布;平行四边形机构减小了空气弹簧的横向力及纵向力,减小了模块的摇头角,有利于曲线通过与导向;运行速度对滑台横移量有一定影响,而轨道曲线半径是影响滑台滑动横移量的主要因素.

| Abstract: | Low-speed maglev train structures and kinematical relationships were analyzed,its dynamics model was developed by using multi-rigid-body dynamics modeling method,the movements of different components of secondary suspension in curve negotiation were analyzed,and the significance of parallelogram mechanism in curve negotiation was explained. Simulation result shows that parallelogram mechanism averagely distributes lateral forces among modules,so that modules are distributed reasonably along the curve. Paral... |
