According to the one-dimensional equivalent circuit of piezoelectric thickness-mode transducer,transmission line theory and ultrasonic propagation theory,a PSPICE equivalent circuit model was proposed.The model can model and simulate the mechanical loss process of piezoelectric transducer by using lossy transmission line.By using this method,the PSPICE equivalent circuit modeling and simulation of the electro-acoustic conversion channel of the ultrasonic wireless transmission system was carried out.The fast and reliable calculation results were obtained,and the circuit design process of the ultrasonic wireless energy transmission system was simplified.This method provides an effective and reliable theoretical and technical basis for the study of ultrasonic wireless transmission system. |
