Description
Summary:The frictional noise without lubrication is studied experimentally and theoretically, when a steel rod fixed at one end is pressed in the radial direction on a rotating thick disk with an angle of inclination. When the rod is inclined to the same direction of the rotation of the disk, rubbing and squeal noise occur and their frequencies become larger with an increase of the rod angle. The higher the mode is, the smaller the rate of increase of frequency is. The variations of the frequency with an increase of the rod angle were calculated by considering only the lateral vibration of the rod. There is a qualitative agreement with experimental results. When the rod is inclined to the reverse direction of the revolution of the disk, chatter noise of a high sound pressure level occurs.
