基于多元高斯声束模型的层状多界面超声声场特性仿真
摘要
Abstract
Aiming at the problems of complex ultrasonic propagation and difficult visualization of sound field distribution in layered multi-interface structures,the expression forms of multi-component Gaussian beam models in single,double and three-layer structures are derived.Water immersion ultrasonic detection method was used to calculate and simulate the sound fields of vertical incidence and oblique emission of 10° to water,water-plexiglass,plexiglass-aluminum-brass,and realize the visualization of the detection sound fields.The simulation results are consistent with the actual theory,which shows that the method proposed in this paper can be applied to the ultrasonic field simulation of layered multi-interface structures.关键词
