Abstract:
A method of estimating a tire performance, comprising the steps of:(a) determining a tire model having a pattern configuration to which deformation can be imparted by at least one of ground contacting and rolling, and determining a fluid model which is partially or wholly filled with a fluid and which comes into contact with at least a portion of the tire model; (b) executing a deformation calculation of the tire model; (c) executing a fluid calculation of the fluid model; (d) identifying a boundary surface between the tire model after the deformation calculation in step (b) and the fluid model after the fluid calculation in step (c), imparting a boundary condition concerning the identified boundary surface to the tire model and the fluid model, and performing the deformation calculation and the fluid calculation until the fluid model assumes a state of pseudo flow; (e) determining a physical quantity occurring in at least one of the tire model and the fluid model in step (c) or step (d); and (f) estimating the tire performance in accordance with the physical quantity.
