Method and device for rapidly stopping vibration system, computer equipment and storage medium

Abstract

The embodiment of the invention discloses a method for rapidly stopping a vibration system. The method comprises the following steps: acquiring a to-be-processed initial vibration waveform; determining an equalization voltage signal of the initial vibration waveform by adopting a preset equalization algorithm; intercepting a voltage signal from a preset position to an end point from the equalization voltage signal as a tail end voltage signal; obtaining an output voltage threshold of a target motor, and determining a first waveform to be spliced according to the initial vibration waveform anda preset position; generating a second waveform to be spliced according to the system resonant frequency of the target motor, the preset position and the first waveform to be spliced; and splicing thefirst to-be-spliced waveform and the second to-be-spliced waveform, and driving a vibration system of the target motor by utilizing the target output voltage, so that the vibration system of the target motor is quickly stopped at the vibration tail end. By optimizing the initial vibration waveform, the design efficiency and the generation efficiency of the target vibration waveform are improved,and the vibration effect of a vibration system of the motor is improved so as to realize a quick stop function of the motor.
