窓ガラスに発生する摩擦振動および騒音の抑制＜研究成果報告＞

When a plate-like object is rubbed by rubber, friction-induced vibration is generated. For reducing the friction-induced vibration, we experimentally investigate the characteristics of the vibration of a rectangular glass plate. The results show that the frequency of the friction-induced vibration is almost the same as the natural frequency of a glass plate. Then, we examine the effect of a dynamic absorber. The results demonstrate that the damping of a dynamic absorber is effective for reducing the friction-induced vibration.
