Abstract

In the toroidal tire cavity, standing waves can occur, leading to very high amplitudes. To investigate the cavity modes, experimental investigations are performed with pulse excitation, on a tire inner-drum test bench and under real operating conditions with a vehicle. At first, fundamental examinations are presented that focus on the identification of cavity modes and on the different system states. In a next step, various excitation mechanisms and important influencing factors are considered.

Abstract

This work systematically describes the mechanisms of tyre/road noise atdriving and braking torque based on measurements with different tyres. The studies on the influence of circumferential force on tyre/road noise can be divided into two different tire tread designs. One sub-chapter reports about a selective influence of force induced tyre/road noise using inclined groove edges. The influence of the circumferential stiffness of the tread blocks on the tyre/road noise is discussed afterwards.
