%X 本文通过COMSOL有限元仿真软件，以单根直导线作为独立阵元建立一维线元式EMAT换能器时域仿真模型，模拟了超声波从产生到传播的全部过程，分析了不同种类超声波特性，为后续换能器设计提供了帮助。<br />
Through COMSOL finite element simulation software, this paper establishes a time-domain simulation model of a one-dimensional linear EMAT transducer with a single straight wire as an independent array element, simulates the whole process of the ultrasonic wave from generation to propagation, analyzes the characteristics of different kinds of ultrasonic waves, and provides help for the subsequent transducer design.
