Abstract

Modern vehicles have well established control mechanisms for power unit noise reduction. On the other hand, noise due to tyre road interaction has become a significant contributor of vehicle interior and exterior noise. Understanding tyre structural dynamics is very important to mitigate the tyre/road noise problem. The objective of this work is to establish a procedure to acquire vibration response data for Operational Modal Analysis (OMA), using a dynamic finite element (FE) analysis. This has been achieved in two stages. Firstly, the experimental procedure is replicated using Abaqus Explicit, a commercial dynamic FE analysis software. Secondly, the tyre dynamic characteristics are determined through Operational Modal Analysis by integrating the explicit FE analysis results with LMS Test Lab software. The modal parameters of the rolling tyre are extracted by the use of polyreference least squares complex frequency domain (LSCF) approach.
