Abstract：The lightweight design of the vehicle body is the development trend of urban railway vehicle technology. However, the lightweight carbody may aggravate the elastic vibration of the vehicle, and cause the decline of the vehicle’s stability and ride comfort during the operation. To effectively suppress the vertical vibration of the elastic carbody of urban railway vehicles and improve the ride comfort of vehicles, taking advantage of the nonlinear change of the system frequency of the variable stiffness mechanism, the vertical dynamic model of the elastic carbody of urban railway vehicles including frequency variable vibration absorber is established, the vibration reduction method of frequency variable vibration absorber to suppress the vertical vibration of elastic carbody is proposed, and the vibration reduction effect of installing frequency variable vibration absorber at different speeds and positions is analyzed, The advantages of frequency variable vibration absorber are obtained. The variable frequency vibration absorber is evaluated by comparing with the traditional variable frequency vibration absorber. The result shows that the frequency variable vibration absorber can effectively suppress the rigid and elastic vibration of vehicles at different speeds and positions. The advantage of a frequency variable vibration absorber is that it can broaden the damping frequency band of the passive vibration absorber to a certain extent, and improve the damping capacity of the vibration absorber under complex working conditions. The work of this paper provides a reference basis for the application of frequency variable vibration absorbers in urban railway vehicles.
