| Abstract: | The nonlinear vertical stiffness characteristic of air spring is simulated with the Nonlinear Finite Element software, MSC.Marc. The influence of several parameters such as inner pressure, angle of fiber, fiber layer number and fiber layer thickness on the vertical stiffness characteristic of the air spring is simulated and analyzed. The simulation result is verified through test, and it indicates that the simulating method used in the paper is reasonable and feasible. |
