Experimental Study of vibration and Noise on Stick-Slip phenomenon of V-belt

Stick-Slip현상에 의한 V-벨트의 진동과 소음에 관한 실험연구

Stick-slip of belt-pulley system produces vibration which results in the noise problem. Experimental study was carried out to investigate the phenomenon of stick-slip with simple v-belt system. The optical displacement sensor detected the vibration caused by the stick-slip of which the frequency was significantly dependant on tension of the belt. The rotation speed of putties also affected the frequency and magnitude of the stick-slip vibration. Existence of misalignment between the driven and drive pulleys made some difference in the stick-slip frequency, but not much. Further study is necessary to identify the generation of noise from the stick-slip vibration.
