Finite Element Analysis of Tire High-speed Uniformity Testing Machine

Abstract

The tire high-speed uniformity testing machine (THUTM) is a testing equipment to measure the mechanical characteristic parameters under the condition of high speed and load, which is a precise detection system with a high added value. In this paper, a finite element model of the high-speed tire uniformity machine is established based on the generating mechanism, test method and factors of tire uniformity. Thereafter, statics and vibration characteristics of the model are analysed and the whole displacement, stress distribution and the dynamic characteristics are obtained. The simulation results show that the designed test system meets the requirement of strength, stiffness and stability. The present research results can provide technical support to improve the structure design and test accuracy of tire high-speed uniformity testing machine.
