Abstract

Measurements of parameters of an acoustic signal excited by own mechanical oscil-lations of a ring made from fiber-reinforced plastics under mechanical impact were carried out; then the annular stiffness of ring was calculated. The method is based on excitation of acoustic signal oscillations, which depend on strength characteristics of the PCM ring.
