Abstract

The invention discloses an adaptive tuning vibration table and a detection method, and belongs to the field of instrument detection. The invention solves a problem that a conventional instrument vibration platform cannot carry out the adaptive control of vibration frequency, and cannot monitor the vibration effect in real time. The vibration table can automatically adjust the vibration frequency of a vibration support, automatically adjusts and controls the vibration amplitude of a to-be-detected instrument, enables the vibration support and the to-be-detected instrument to resonate, and modulates a frequency for resonance, so as to achieve the maximization of the vibration amplitude of the instrument. The vibration table can impact the instrument in the maximum range, and the whole vibration process is monitored in real time. The method achieves the quantitative measurement of instrument parameters. The vibration table is mainly used for the detection of the to-be-detected instrument.

Description

technical field [0001] The invention belongs to the field of instrument detection. Background technique [0002] At present, the instrument detection vibrating table is large, complex and expensive, and the accuracy rate of the instrument calibration is low. The existing instrument detection vibrating table can realize the vibration of the instrument, but there is no quantitative measurement of the vibration amplitude, vibration frequency, and vibration time. At the same time, the vibration process is not controlled, and the effect of vibration cannot be monitored in real time. SUMMARY OF THE INVENTION [0003] The present invention is to solve the problems that the existing instrument vibration table cannot perform adaptive control on the vibration frequency and cannot monitor the vibration effect in real time; the invention provides an adaptive tuning vibration table and a detection method. [0004] An adaptive tuning vibration table, which includes a camera, a PC, a co...
