Abstract:
A method of designing a tire which takes into consideration actual conditions in the presence of a fluid, such as drainage performance, on-snow performance, noise performance, and the like. A tire model and a fluid model including the shape, structure, and the like are constructed, and a road surface condition is inputted (steps 100 to 106). Boundary conditions during tire rolling or tire nonrolling are set (step 108), deformation calculation and fluid calculation of the tire model are performed (steps 110 to 114), and a boundary surface between the tire model and the fluid model is recognized to update the boundary conditions (steps 118 and 120). The result of calculation is outputted as the result of estimation, and based on this result of estimation, main travel paths of the fluid, i.e., streamlines, are adopted (step 122), grooves are formed along the determined streamlines so that a tire model with patterns is constructed (steps 124 and 126), and the draft design having satisfactory performance is adopted (steps 128 to 132).
