<p>PROBLEM TO BE SOLVED: To provide a method that simulates behaviors of tires of vehicles under travelling conditions on grounds.SOLUTION: A method according to the present invention is configured to have a mechanical model that essentially computes longitudinal stress (Fx) and transverse stress (Fy) transmitted by a tire between a ground and a vehicle in accordance with dynamic parameters related to the physical conditions for the tire running and use and in accordance with physical tire-specific parameters. According to the present invention, the mechanical model is set assumption that a contact surface of the tire in contact with the ground has an adherence contact area and a sliding contact area, and a unique x-coordinate point b expressing a transition exists between the two contact areas, and solve the longitudinal stress and transverse stress in an iterative manner (8 to 10). Industrial applicability is to simulate the dynamic behavior of the vehicle in real time.</p> |
