Identify challenges in vibration measurements for rotating tyres using a finite element model

Abstract

In the current paper, the measurements from a tyre testing on a dynamometer are replicated using a finite element analysis to identify the feasibility of obtaining mode shapes using rotating tyre data. Performing vibration analysis using computer-aided engineering (CAE) reduces the human effort of executing the complex experimental setup and performing the tests. Furthermore, it provides test engineers with an understanding of the dynamic performance of tyres. In this work, an explicit finite element analysis was performed on the rolling tyre. Using the data from the simulation, an operational modal analysis was performed to extract the modal parameters of the tyre in the rolling condition. The results are analysed with those obtained from the experimentation of the Kettering Formula SAE (FSAE) tyre.
