Abstract

It was difficult for the traditional analytical method to analyze the acoustics characteristics of acoustics sensors. In order to solve the problem, a method based on the Finite Element Method (FEM) was investigated combining with the technology of harmonic response analysis. After presenting the basic math method theory of finite element, the harmonic response analysis model of ultrasonic liquid level transducer was simulated by ANSYS software package, and its corresponding acoustics parameter was illustrated. The simulation results showed that the ultrasonic probe has a good directionality and its resonant frequency is 1.01MHz; the energy of the acoustic beam is focused on the clearance of probe between transmit and receive; in the design for the transducer, the probe should be mounted in the region of maximum pressure amplitude of underwater ground field.
