Due to the layout of the door in the middle of the carbody and air-conditioning installation hole at the top, the flexural rigidity of carbody structure decreased obviously based on the modal frequencies calculated by finite element model (FEM) .Dynamic vibration absorber (DVA) was applied to restrain the vibration of the carbody. A 3D rigid-flexible coupled vehicle dynamics model was established by combining the multibody dynamics theory with the FEM and underneath equipment to measured track excitation. The traction converter with high weight is selected to be the only underneath equipment. The result shows that the elastic connection between carbody and traction converter has a significant influence on carbody vibration. Compared with the rigid connection, the elastic connection can reduce the vibration of carbody to a large extent. The reduction of vertical vibration is more obvious than the lateral vibration. The underneath equipment of carbody can be regarded as a dynamic vibration absorber(DVA) to reduce the flexible vibration of carbody. Besides,, the suspension parameters of elastic connection greatly affect the vibration of carbody and traction converter.
