摘要：
Vibrational diagnostics of scoring on coupling faces of the liner and the piston in a cylinder-and-piston group is considered. Wavelet transformations are used to study specific manifestations of a defect in the vibroacoustic signal. A method is proposed to employ the obtained information for generation of a diagnostic signature of scoring that may be used in automated diagnostic systems.
