Abstract

The invention discloses a novel beam vibrating frequency recognition system and method. The recognition system is composed of a vibrating frequency recognition assembly (101) and a vibrating frequency generating assembly (102), wherein the vibrating frequency generating assembly (102) can give out frequency signals of needed vibrating frequency on a beam (1), and vibrating signals with different frequencies can be given out by adjusting a signal generator (5); the vibrating frequency recognition assembly (101) can perform frequency sweeping in the 10-10100 Hz frequency band on a second piezoelectric ceramic chip (3) through an impedance analysis meter (4), the second piezoelectric ceramic chip (3) senses the vibrating signals in the frequency sweeping process, the piezoelectric impedance values of the impedance analysis meter (4) have the characteristic similar to same-frequency resonance, and the vibrating frequency signals which are transmitted by the medium beam (1) and given out by the vibrating frequency generating assembly (102) are found through graph changes of vibrating points in frequency sweeping.

Description

Technical field [0001] The invention relates to the technical field of a novel beam vibration frequency identification system and method. Background technique [0002] Vibration phenomena are widely present in nature and human production and life. The measurement of vibration parameters, especially the measurement of vibration frequency, is self-evident. So people invented various methods and instruments for measuring vibration frequency. In summary, it can be divided into two categories: contact measurement and non-contact measurement. The measurement of contact vibration frequency is based on the measurement of the acceleration of the vibrating object, and the sensor needs to be pasted on the vibrating object. Non-contact measurement mainly includes electromagnetic and optical measurement methods. They also have obvious limitations. For example, electromagnetic measurement methods have poor anti-electromagnetic interference ability and complex sensor installation; while opti...
