Sound radiation due to tire tread vibration
Sound radiation due to tire tread vibration
A theoretical model was studied to describe the sound radiation created by surface vibration of in-service tires. The tire is modeled as a circular ring model. The effects of normalized frequency and the structural loss factor are included. The radiation sound power is calculated as a function of the normalized frequency and the structural loss factor through numerical integration of the sound pressure. The basic sound radiation mechanism is shown to be a damped progressive wave field on the structure in the vicinity of the applied force. The result indicates that the potential sound reduction might be obtained if the values of the normalized frequency and structural loss factor are determined.
