METHOD, APPARATUS AND PROGRAM OF SIMULATING TIRE ABRASION

摘要

PROBLEM TO BE SOLVED: To accurately simulate tire abrasion. SOLUTION: A method of simulating the tire abrasion includes steps of creating a tire model including a plurality of elements of a tire divided (step 100); setting simulation conditions regarding deformation calculation of rolling of the tire model (step 102); carrying out the deformation calculation of the tire model (step 104); calculating abrasion energy (step 106); calculating an abrasion loss corresponding to the abrasion energy, based on nonlinear correspondence between the abrasion energy and the abrasion loss (step 108); carrying out the steps 102-108 under a plurality of simulation conditions (step 110); calculating an average value of a plurality of abrasion losses (step 112); correcting the tire model based on the average value of the abrasion loss (step 114); carrying out the steps 102-114, until completion conditions are satisfied (step 116); and outputting calculation results (step 118).
