Mechanical vibration measurement device based on piezoelectricity of piezoelectric ceramics

Abstract

The invention relates to the technical field of vibration measurement, and discloses a mechanical vibration measurement device based on piezoelectricity of piezoelectric ceramics, which comprises a supporting plate. A sealing plate is fixedly mounted in the supporting plate, and uniformly distributed connecting torsion springs are fixedly mounted between the sealing plate and the supporting plate. According to the mechanical vibration measurement device based on the piezoelectricity of the piezoelectric ceramics, when the supporting plate shakes along with vibration, the connecting torsional spring can effectively convert received left-right shaking force into up-down shaking force, the shaking force is conducted through the piezoelectric rod, the piezoelectric rod converts mechanical energy into electric energy under the action of the shaking force, the driving wheel can be driven to rotate, the driving wheel can be matched with the connecting wheel to drive the moving rod to move in the connecting frame in the rotating process, then the fixed wheel is driven to rotate, the fixed wheel is matched with the permanent magnet block in the rotating process, induced current can be generated, and therefore mechanical energy of vibration can be converted into electric energy; and the vibration detection effect is realized.

Description

technical field [0001] The invention relates to the technical field of vibration measurement, in particular to a mechanical vibration measurement device based on the piezoelectricity of piezoelectric ceramics. Background technique [0002] Vibration measurement refers to detecting vibration changes, converting them into corresponding electrical signals that are easy to display, analyze and process, and extracting useful information from them. Solving vibration problems requires not only theoretical calculations, but also vibration in many cases In addition to the necessary sensors and instruments for test analysis and vibration measurement, it is also necessary to master the correct measurement method in order to obtain reliable data and correct results. [0003] At present, in the process of measuring mechanical vibration, it is generally used to convert the vibration change into an electrical signal, but in the conversion process, because the vibration frequency cannot be ...
