Method for predicting remaining resource of product in its cyclic loading, involves measuring passage time of signals between piezoelectric transducers based on product load cycles

摘要

The method involves measuring the passage time (T) of the signals between the piezoelectric transducers based on the product load cycles. The testing on the fatigue of three samples is performed from the material of the product in the greater resistant load amplitudes, if the destruction of the patterns occurs in the course of acceptable load cycles. The pattern is unloaded during the measurement of the passage time of the signals.
