Elastic waves generated during friction are considered to be a source of information on the processes of deformation, fracture, and adhesive interactions in the friction contact zone. Results of computer simulations show that, in view of the dynamic nature of friction, the analysis of acoustic signals detected even in a steady-state regime requires applying frequency-temporal techniques in addition to the Fourier transform. It is concluded that the laws of frictional wear can be studied by analyzing the corresponding acoustic spectra.
