Study on Frictional Vibration

In this paper, frictional vibrations are experimentally investigated. The experiments are compared with the theoretical analysis in the previous report. The obtained results are as follows : 1. Amplitude characteristic from experiments is agree well with the theoretical analysis which includes a time effect. 2. The time effect of frictional characteristic is important factor to determine the limit of vibration. 3. The critical driving velocity Vc is given by a following equation; Vc=c/wn2 c; constant, wn ; natural frequency.
