Abstract

The invention discloses a device and method for measuring the amplitude of the output end of an ultrasonic acoustic system. The problems that in the prior art, the amplitude displacement is difficult to calibrate and correct, and the precision is poor. The device for measuring the amplitude of the output end of the ultrasonic acoustic system comprises a base plate, a stepping motor, a precise micro gauge, a gauge support, a sleeve, a laser transmitter, a sensor support, a laser sensor, a main support, a fixing plate, a flange plate, an amplitude change rod, a piezoelectric transducer, an ultrasonic generator and a single-chip microcomputer control system. The device for measuring the amplitude of the output end of the ultrasonic acoustic system has the advantages that operation is convenient, the measurement precision can be improved, and the device is suitable for measuring the amplitudes of the output ends of ultrasonic acoustic systems at any frequencies and amplitudes, and the application range is wide.

Description

technical field [0001] The invention belongs to the field of measurement, and in particular relates to a device and method for measuring the amplitude of an output end of an ultrasonic acoustic system. Background technique [0002] Nowadays, ultrasonic processing is widely used in the fields of industry, agriculture, national defense, medicine and health, and environmental protection, and is constantly expanding new application fields. [0003] The amplitude of the output end of the ultrasonic acoustic system is an important performance index that characterizes the output power of the ultrasonic system in ultrasonic vibration processing. Since the output power of the horn is proportional to the square value of its amplitude displacement, the amplitude of the ultrasonic horn can be measured to obtain The sound intensity of power ultrasound, etc., is of great significance to ultrasound and related research. But there are not many reports about the measurement method of ultras...
