| Research Abstract |
Vibration character of the frictional contact surface between a disk and a pad influence squeal generation and squeal frequency on the disk brake. In this research, we developed the device to measure the dynamic stiffness of frictional contact surface in the continuous slipping and squeal generating condition. Influence of surface property of the pad and rotation speed of the disk on the vibration character is measured. The measurement results clarify that the stiffness of contact surface is decrees at a continuous slipping condition. This decree of stiffness influence squeal generation in low pressure braking.
