| Abstract: | Based on the experimental study of nonlinear rubber suspension system of the construction vehicle, a nonlinear dynamic model is established, which can be solved by the Runge-Kutta method integrated in the Simulink software. In computer simulations with this model, the response in time domain such as RMS value of each test point is derived and the simulation results coincide well with that of the random input test. This indicates both the nonlinear dynamic model and the simulation model are correct, so it can be applied to assess and analyze the vibration attenuation performance of the suspension. The model provides a valuable base for the parameter optimization of the rubber suspension. |
