| Abstract: | In the paper, the contact characteristics between tire and road are analyzed. The vehicle loading system is simplified as a two DOFs vibration system. A flexible roller contact model is presented, which takes the geometric filtering effect and flexible filtering effect into account. The simulations of effective input are carried out based on the rigid and the flexible roller contact models. Simulation results of a vehicle vibration system with roller contact models (especially flexible roller contact moldel) show their good agreement with experimental data. The established model can be applied to the analysis of vibration and dynamic load of vehicles. |
