Abstract

This paper studys on the determination of elastic modulus of amorphous alloys by acoustic method. The method is simple and effective, convenient and fast, non-destructive and has strong practical significance. A cantilever beam structure is selected, and the non-contact acoustic measurement and analysis system is composed of MM 210 microphone, DT9837 series data acquisition unit, computer and dewesoft7.0 software. The vibration of the specimen is generated by the transient vibration, which generates a sound wave, and the inherent frequency is obtained by the sensor data acquisition and software analysis. According to the theoretical formula of the inherent frequency of the cantilever beam, the elastic modulus of the amorphous alloy is calculated, at the same time, the measurement results are compared with the three-point bending test method. Finally, the finite element method is used to verify the inverse analysis.
