This paper analyses the influence of the additional stiffness function of the traction bar on the vehicle vertical dynamic performance. Based on the subway vehicle dynamics model, the influences of the additional stiffness function of the traction bar on vehicle’s response to vertical impact, carbody vertical ride index and relevant phenomena of wheelset longitudinal vibration resonance were analyzed. Results indicate that the additional stiffness function of the traction bar will increase the stiffness of the secondary suspension system. It not only increase the response of the vehicle to vertical impact and reduces the ride comfort of vehicle, but also increase the vertical and longitudinal vibration acceleration, and the vertical dynamic load of the first and secondary suspension increased too. Put forward that the vertical dynamic performance of the vehicle can be improved through decrease the connection stiffness of the traction bar to 25% of the present value.
