<P>PROBLEM TO BE SOLVED: To improve the evaluation accuracy of durability when evaluating the durability of a tire by simulation using a computer. <P>SOLUTION: A tire model is created (Step S101), and at least one of the stress and stain of the tire model is arithmetically operated (Step S102). Next, at least one of the stress and stain of an element adjacent in the peripheral direction of the tire model is successively acquired, and a change history of at least one of the stress and the strain is created (Step S104). Fourier transform is performed on the change history of at least one of the stress and the strain (Step S105). Afterwards, an index for evaluating the durability of the tire is created by using at least one of an amplitude of the stress and an amplitude of the strain after the Fourier transform. <P>COPYRIGHT: (C)2012,JPO&INPIT |
