Method for modeling a tire model and simulation method

摘要

A method for modeling a tire model (13) used for a computer simulation of a pneumatic tire with a toroidal main body and a circumferentially extending tread pattern formed thereon, comprises the steps: providing a three-dimensional main body model (11) by dividing the main body by N (N is an integer not less than 2) equally in a circumferential direction of the tire using a finite number of elements; providing a three-dimensional pattern model (12) by dividing the tread pattern by M (M is an integer greater than N) equally in the circumferential direction of the tire using a finite number of elements; coupling the pattern model (12) with the main body model (11) to make a three-dimensional tire model, and moving nodal points existing on a radially outer surface of the pattern model (12) such that a thickness of the pattern model (12) measured from a radially outer surface of the main body model (11) in a normal direction becomes constant.
