ANALYSIS METHOD OF TIRE PERIPHERAL SPACE, COMPUTER PROGRAM FOR ANALYZING TIRE PERIPHERAL SPACE, AND ANALYZING DEVICE

摘要

PROBLEM TO BE SOLVED: To suppress a reduction in the calculation accuracy when analyzing a phenomenon which develops in space existing around a tire.;SOLUTION: The tire is divided into a plurality of elements constituted by a plurality of nodes, thereby creating a tire model 10. The tire model 10 is brought into contact with a road surface model 12, and ground contact analysis is performed. Next, a surface region 21 is created based on a physical quantity of each nodes on a surface of the obtained tire model. Secondly, a boundary portion 22 which partitions the interior and exterior of the tire surface region is provided in the surface region 21. A space model 30 is created by use of a tire boundary region, a contact surface region 24 of the road surface model 12, and a hemispherical region 15, and a phenomenon which develops in the tire peripheral space is analyzed by use of this space model 30.;COPYRIGHT: (C)2012,JPO&INPIT
