Abstract
This paper establishes the vertical nonlinear dynamic model of the air spring system and the dynamic model of a high-speed train.Based on the test results of the vertical vibration transmission of the air spring,the accuracy of the nonlinear dynamic model of the air spring is verified,and the vertical dynamic stiffness characteristics and vibration transmission law of the air spring are analyzed by numerical simulation.The effects of secondary anti-roll torsion bar stiffness,air spring orifice diameter,and secondary vertical damper damping on the vibration transmission law are studied,and the effects of different secondary suspension structures on vehicle dynamics are compared.The simulation results show that the diameter of the orifice has a great influence on the dynamic stiffness and transmissibility of the air sprin,and reducing the diameter of the orifice will increase the vertical dynamic stiffness of the air spring.The application of the orifice method is beneficial to improve the high-frequency vibration reduction effect,and the vertical damper is conducive to low-frequency vibration reduction.The results show that the vibration transmissibility similar to that of the secondary vertical damper can be achieved by using the appropriate diameter orifice,and the vertical stability index and the vertical acceleration of the vehicle body can be reduced.关键词
