Abstract

The noise generated from a treadband mechanism of a tire has been the subject of this research. In particular, the treadband has been treated as an infinite tensioned beam resting on an elastic foundation which includes damping. The main objective is to predict the sound power generated from a system mentioned above by locating harmonic point forces representing the excitation of treadband at the contact patch. It is possible to predict the sound power radiated from this structure by using wavenumber transformation techniques. In order to find out the minimum radiated sound power, All parameters were varied. Thus, this model can be used as a tire design guide for selecting parameters which produces the minimum noise radiation.
