车体与车下设备的耦合振动研究

Coupling vibration research of the equipment on the car body and under the vehicle

为研究车体与车下设备的耦合振动,基于刚柔耦合动力学模型比较了多刚体与刚柔耦合两种模型车体和设备振动的具体差异,研究了一系垂向刚度对耦合振动的影响,最后优化了变压器的吊挂刚度和频率。

In order to study the coupled vibration of the equipment on the car body and under the vehicle,the specific differences of the car body and equipment vibration between the multi-rigid and rigid-flexible coupled models were compared on a basis of the rigidflexible coupled dynamic model,and the effects of the primary vertical stiffness on the coupled vibration were studied.Finally,the suspension stiffness and frequency of the transformer were optimized.
