| Popis: | 102 The purpose of this work is to study the rolling contact responses of inflated pneumatic radial tires with a quarter vertical car weight loaded initially. Structure of tire contains the rubber tread and reinforcing composite layers (i.e., the inner layer, carcass, bead filler and bead wires). The Mooney-Rivlin constitute law was adopted to describe the large deformation and non-linear behavior of rubber material. The classical laminated theory was used to model the mechanical responses for the reinforcing composite layers. In the present study, the 235/45R17 radial tires with three tread patterns were chosen to study the dynamic contact rolling responses when tires rolled on a dry pavement. Finite Element Commercial Codes – LS-DYNA was used to simulate the smooth pattern tire’s quasi-static response in order to compare the normal contact forces obtained from both FEM commercial codes and compressive test data. The result revealed that experimental data for the wheel compressed on the compression device had consistency with LS-DYNA simulated normal contact forces. Current LS-DYNA tire models were then used to simulate the process of the tire side slip rolling under different conditions (i.e., different vertical loading, coefficient of friction and rolling velocity). By observing the relationship between tire contact pressure and tire wear, then we predicted the wear of tire when tire side slip rolling under different slip angle. |
