摘要
采用机车—轨道耦合动力学理论与方法，研究了电传动机车与轨道的动态相互作用问题，以抱轴式驱动系统电力机车为例，建立了机车—轨道相互作用统一模型，运用ＶＩＬＴ仿真软件分析比较了弹性和刚性抱轴式电传动机车对轨道的动力作用以及牵引电机的振动特性。文章还讨论了牵引电机各种悬挂方式对轮轨动力学性能影响的特征。
The theory and method of locomotive track coupling dynamics are applied to investigating the dynamic interactions between electric drive locomotive and track.Locomotive with axle hung traction motor is chosen to set up a unified model for locomotive track interaction.By means of simulation software VILT,the dynamic effects of locomotive with elastic or rigid axle hung motor on track,as well as vibration property of the traction motors are analysed and compared.Influence of different suspension modes of traction motors on wheel/rail dynamic performance is also discussed,and applied scopes are inferred.
