Abstract: In order to decrease the impact and vibration induced by impact roller during its working, the characteristics of influence of the cushioning system's parameters on the impact load acted on the tractor were studied by simulation. The dynamic equations of cushioning system were established through analyzing the structure and work performance of the impact roller. The solid model of the whole machine was set up in UG software and was transformed into ADAMS that is multi\|body dynamic simulation software. The dynamic model was established with the tire and the road, and the dynamic characteristics of the whole machine were simulated under typical work conditions. The simulation results were compared with test data, which validates the correctness of the simulation model. Utilizing parametric design research method, the model was parameterized and the variations of traction load were simulated and analyzed when the system's stiffness and damping parameters changed. The sensitivity curves and load curves were achieved and the rational ranges of parameters were presented. The results show that the first level damper and the second level stiffness have much greater effect upon the traction load than the other parameters, and the whole machine's simulation model is able to simulate the work condition of impact roller and provides the references for eng
