Abstract

ABSTRACT
The present study is concerned with evaluating the pin-on-disk test rig usage and the
measurements conducted in recognizing the occurrence of stick-slip phenomenon. The
test rig consists of two separate blocks to ensure that the vibration of the elastic disk
and the emitted noise are completely adverted to friction between the moving pin and
the stationary steel disk.
The occurrence of stick slip is clearly picked up using the near field noise
measurements. It can be distinguished from the vibration signal as high consecutive
spikes, but the existence of these spikes is clearer and more definite in the noise
signature.
