Abstract

The invention relates to the technical field of power generation, in particular to a vibration testing system. An arbitrary waveform signal generator generates voltage signals with various frequenciesand waveforms; after amplification by a power amplifier, a piezoelectric vibrator is driven; a laser camera of a high-precision laser vibration meter collects reciprocating vibration of the piezoelectric vibrator; and the data are transmitted to a multifunctional laser Doppler vibrometer analyzer to obtain vibration deformation and vibration waveforms of the piezoelectric vibrator under differentworking conditions. Therefore, the vibration test of the piezoelectric vibrator is realized.

Description

technical field [0001] The invention relates to the technical field of power generation, in particular to a vibration test system. Background technique [0002] At present, for some moving parts, mechanical energy will also be generated during the working process, for example, vehicle tires will be deformed during the rotation process, which will generate mechanical energy. Whether the mechanical energy produced by shoes or tires will be lost in the air in vain. That is to say, the existing moving parts such as shoes and tires fail to collect and utilize the mechanical energy generated by them, resulting in a waste of energy [0003] With the development of electronic technology, piezoelectric ceramics can convert these mechanical energies into electrical energy. Piezoelectric wafers formed by the positive piezoelectric effect or inverse piezoelectric effect of piezoelectric technology have been widely used in many fields, such as piezoelectric motors. , piezoelectric pump...
