Factors determining elastic wave generation at friction. Simulation on the basis of discrete-continual approach
The model of mechanical interaction in contact spot at sliding friction has been examined on the basis of discrete-continual approach. Frequency spectrum of occurring elastic waves was analyzed, presence of frequencies depending on profile roughness of interacting surfaces was shown. Analysis carried out by Fourier- and wavelet-transformations allowed determining complex structure of elastic waves occurring at friction. The conclusion was drawn that the laws of wear process may be studied on the basis of the analysis of proper acoustic spectrum.
