Method of simulating rolling tire

Abstract

A method of simulating rolling tire comprises the steps of: modeling the tire in finite elements to make a tire model which comprises a first element having a viscoelastic property; modeling a road in finite elements to make a road model; executing a numerical simulation in which the tire model is made to roll on the road model at a predetermined condition; obtaining six kinds of strains in time sequence from the first element of the tire model with rolling, the six kinds of strains including three kinds of normal strains along a tire meridian direction, a tire circumferential direction and a tire thickness direction, and three kinds of shear strain along the tire meridian direction, the tire circumferential direction and the tire thickness direction; and calculating energy loss of the first element based on the six kinds of the strains.
