The invention provides a method and a device for measuring mechanical resonance frequency as well as a storage medium and a measuring instrument. The method for measuring the mechanical resonance frequency comprises the following steps: detecting an analog voltage signal of to-be-detected equipment; converting the detected analog voltage signal into a digital signal; processing the converted digital signal by using fast Fourier transform to obtain to resonance frequency of the to-be-detected equipment. The technical scheme provided by the invention has the advantages that the mechanical resonance frequency of the to-be-detected equipment can be measured quickly, accurately and effectively, a good guiding effect for suppressing mechanical resonance of the to-be-detected equipment and debugging parameters is realized, the debugging speed of the to-be-detected equipment is increased, and further stability, quickness and accuracy of operating the to-be-detected equipment are improved.
Description
technical field [0001] The invention relates to the technical field of detection, in particular to a method, device, storage medium and measuring instrument for measuring a mechanical resonance frequency. Background technique [0002] Usually, the equipment will generate vibration and noise during operation. Take the servo system as an example. At present, when the mechanical rigidity of the servo system is low, vibration and noise will be generated due to the resonance caused by the shaft twist, which seriously affects the control of the servo drive. precision and responsiveness. Accurate and effective measurement of the mechanical resonance frequency of the servo system is a problem that needs to be solved at present. The prior art uses an eddy current vibration sensor to measure the mechanical resonance frequency. The eddy current vibration sensor is a sensor made of eddy current effect to measure the vibration of an object. It can measure the static and dynamic relativ...
