Stick-slip detection through measurement of near field noise

The paper presents an experimental investigation to recognize the occurrence of the stick-slip phenomenon. As a trial to detect and evaluate this phenomenon, a pin on disk test rig is presented. The test rig consists of two separate blocks to ensure that the vibration of the elastic disk and emitted noise are completely adverted to friction between the moving pin and stationary steel disk. The occurrence of stick slip is clearly picked up using near field noise measurements. It can be distinguished from the vibration signal as high consecutive spikes, but the existence of such spikes is clearer and more definite in the noise signature.   Key words: Pin on disk, friction, induced vibration, noise, and stick-slip.
