ANALYSIS DEVICE, AND METHOD AND PROGRAM THEREOF

摘要

PROBLEM TO BE SOLVED: To provide an analysis device that sets a support range so that a solution can be stably obtained.

SOLUTION: The analysis device 30 that analyzes a tire 100 by mesh-free method, includes an input part 32 into which a three-dimensional tire model 6 divided into sub-cell regions 4 by a plurality of node points is inputted; and an analysis part 34 that sets each three-dimensional oval support range 7 at the center of each of the node points, and obtains an approximating function indicative of displacement in the support range 7 by using three-dimensional position information on the node points included in the support range 7 and a kernel function where a weight factor is determined according to a distance from each of the node points of the support range 7 and the node point at the center.
