Influence of Wheelset Flexibility on Dynamic Response of Linear Induction Motor Vehicles

  • 摘要: 直线电机地铁车辆有内置和外置两种轴箱布置方式,针对这两种轴箱布置的直线电机地铁车辆,分别建立了考虑轮对柔性的直线电机地铁车辆-轨道耦合动力学模型. 模型中轮轴采用欧拉梁模拟,考虑轮对柔性变形对一系悬挂作用力、电机吊杆力以及轮轨空间动态相互作用的影响,对比分析了在轮轨不平顺激扰作用下,轴箱内置和外置直线电机地铁车辆轮对柔性响应特性及其对系统动态响应的影响. 研究结果表明:相比于刚性轮对模型,两种直线电机地铁车辆柔性轮对模型求解所得轮轨垂向力响应均存在77 Hz的主振频率峰值,对应于轮对的一阶弯曲模态频率;当考虑轮对柔性效应时,相比于轴箱外置直线电机地铁车辆,轴箱内置直线电机地铁车辆的轮轨垂向力更大,气隙更小.
