Wavelet frequency spectrum analysis vibration aging device

The technical scheme of the invention relates to a wavelet frequency spectrum analysis vibration aging device. The device comprises a piezoelectric sensor, a shock vibration motor, a shock excitation controller, a wavelet frequency spectrum analysis controller, a displayer, a printer, a keyboard and the like; according to the device, through wavelet analytic transformation, information is effectively extracted from a signal; at the same time, through calculation functions of dilation and translation, multiscale detailing analysis is carried out on a function or the signal; ultimately, time subdivision of high-frequency positions and frequency subdivision of low-frequency positions are achieved so as to focus on any detail of the signal; then with combination of fast Fourier transformation, the purposes of decomposing the signal and extracting different frequency components are achieved, dozens of harmonic frequencies of a workpiece are found out, five harmonic frequencies with different vibration types and ha
