Study on energy transmission through metal wall based on piezoelectric material
Laboratory of science and technology on integrated logistics support, National University of Defense Technology, Hunan Changsha, China
The efficiency of electric energy transmission through metal wall by ultrasonic wave mainly depends on the relevant parameter of the sandwich structure system, which is consist of a transit piezoelectric transducer, a receive piezoelectric transducer and a metal wall. This paper discussed the characteristics measurement of piezoelectric energy transmission channel through metal wall based on a kind of piezoelectric transducer. First, the intrinsic impedance characteristic of piezoelectric transducer is measured using a high precision impedance analyzer. Then ultrasonic energy transmission channel through a metal wall testing system is analyzed. The voltage ratio under different frequencies of the channel is measured and the maximum energy transmission frequency is obtained. Mason model is verified and compared with the experimental results, which provides a beneficial reference for further researches on ultrasonic through metal wall energy transmission.
