Abstract
The present disclosure provides a method for generating a motor vibration wave, including the following steps: step S1: exciting a motor by a white noise signal, and measuring a vibration signal of the motor by an acceleration sensor; and step S2: obtaining an impulse response of system based on the vibration signal obtained by the acceleration sensor; and step S3: constructing an expected vibration waveform; and step S4: performing Wiener inverse filtering on the vibration waveform obtained in step S3 to obtain a frequency-domain signal; and step S5: performing inverse fast Fourier transform on the frequency-domain signal obtained in step S4 to obtain an excitation signal in time domain. With such method for generating a motor vibration wave provided by the present disclosure, the expected vibration waveform can be automatically generated and conveniently extracted.
