Tire Modal Analysis of ANSYS and Hypermesh Under Co-simulation

Abstract

The paper is aimed to analyze and get a further understanding of the dynamic characteristics of the tire by means of computing modal analysis. A tire modal testing system is built on the basis of the previous studies. We also attempt to study how the amplitude of exciting force and loading changes affect the tire modal test, which lays a foundation for applying the tire modal test into practical use. Besides, the relations of experimental modal and computing modal will also be analyzed. The analysis and application of the tire modal lay a solid foundation for medium-high frequency tire mechanical model which is being established by our research group. And it takes advantage of HYPERMESH and ANSYS to set up the finite element model of the tire and to analyze the tire structural dynamics, laying a foundation for setting, recognizing the correctness of experimental modal parameter as well as studying the relationship between calculating modal and experimental modal. And it also studies the law of tire's dynamic characteristics and its reason. The third part makes a summary of the full text.

Analysis of Inflated Structures: A Case Study on Analysis of Automobile Tyre Using Ansys

“…It was used without any steel insertion and with a smooth tread surface, without ribs and grooves. In the next phase to achieve performance as close as possible to the real tire, by using steel-cords and beads in different configurations more complex models were realized in the CAD system, [3]Another research by Wang Qingchao, Song Wanqing, Liang Jiankai is aimed to analyze and get a further understanding of the dynamic characteristics of the tire by means of computing modal analysis. On the basis of the previous studies a tire modal testing system was built on.…”
