TIRE MODEL, AND TIRE BEHAVIOR ANALYSIS DEVICE, METHOD, AND COMPUTER PROGRAM USING TIRE MODEL

摘要

PROBLEM TO BE SOLVED: To provide a tire model capable of capturing a fine tread thickness fluctuation while suppressing the calculation cost.SOLUTION: The tire model using a finite element method includes a joint part 20 in which members constituting a tire are bonded together. The tread thickness of the joint part 20 is different from that of a non-joint part 21. The angle of one element in the tire circumferential direction in the joint part 20 is narrower than that in the non-joint part 21.
