【 摘 要 】

Abstract In view of the fact that exhibits monorail transportation in recent years, the good situation and the lack of straddle-type monorail vehicle vertical dynamics research, the key problems of vertical vibration were studied in this paper: The vertical coupling is between walking tires and finger-band. A dynamic model based on the vertical equivalent stiffness of tire is proposed, the force mode of the tire is determined through the comparison calculation and the dynamics model between walking tires and finger band was established on ADAMS Dynamics Software. By dynamic calculation, the vibration of four running wheels in time and frequency domains is obtained, and the vibration of the front axle of the front bogie is studied in detail; the correctness of the model is confirmed by comparing with the real vehicle test. Finally, the limitations of this paper and the direction of follow-up work are discussed.
