TIRE PERFORMANCE PREDICTION METHOD, GROUND SIMULATION METHOD, TIRE DESIGN METHOD, RECORDING MEDIUM, AND TIRE PERFORMANCE PREDICTING PROGRAM

摘要

PPROBLEM TO BE SOLVED: To easily and precisely predict tire performance such as traction of a tire when traveling on the ground. PSOLUTION: A method includes: steps of creating a tire model, and creating a field model, based on a measured data after measuring an actual field (steps 100-104); setting a boundary condition (step 108); calculating a deformation of the tire model (step 110); calculating a deformation of the field model (step 112); calculating pressure or the like of the field on a tire surface (step 114); calculating a frictional force acting on the tire (step 116); recognizing a boundary face of the field in response to the deformation of the tire model to add the boundary condition (step 118); and adding a surface force added with the frictional force, to the tire model, to thereby output and evaluate the results (step 122). Such the result output and evaluation of the tire performance are repeated in the method (step 122-134). PCOPYRIGHT: (C)2009,JPO&INPIT
