概要
- 論文の詳細を見る
Vibration and noise of a damped wheel are investigated theoretically and experimentally. A dynamic damper composed of a rubber and a steel thin annular plate is attached to the web of a conventional wheel. In the theoretical analysis, the rubber is assumed to be a spring with viscous damping. The results show that the vibration and noise can be considerably reduced by the dynamic damper. When the fundamental frequency of the dynamic damper becomes equal to the natural frequency of the wheel, the vibration is remarkably decreased. In order to have an effective reduction of the vibration and noise, the rubber should have a large loss factor and the damper should be attached to the outer side of the wheel.
