110 ディスクブレーキパッドの静圧縮時の剛性と微小振幅加振時の剛性(OS4 機械の振動・騒音および制御に関する新技術(2),研究討論セッション)
詳細
This research considers that relationship between pad stiffness in static condition and vibrating condition. It is clarified that pressure dependency of pad stiffness is the cause of squeal in a past study. The stiffness when vibration is added to a pad is more than twice as large as the stiffness in static condition. Semi-static stiffness of the pad is measured by applying large-amplitude and low-frequency vibration to the pad. The pressure-displacement characteristics of the pad exhibited hysteresis. When the amplitude is decreased, average stiffness of the pad increase and it approaches the stiffness in dynamic condition from static stiffness.
