摘要
电动换能器的设计涉及电磁场和声-结构耦合问题,本文利用COMSOL多物理场分析软件提供的该两种分析模块进行组合,以电磁理论为基础推导出了适合COMSOL数值计算的公式,把两种耦合场的分析结合起来,利用电磁场分析过程计算所需要变量,代入声-结构耦合场进行分析,得到声场分布情况。文章也大致介绍了COMSOL的有限元建模和该两种模块的使用方法。本文对电动换能器结构如何优化不做讨论。
Electric transducer design includes electromagnetic field and acoustic-structure coupling. This paper use COMSOL multi-physics analysis software which provides the two analysis modules to be combined. Deduced a formula for COMSOL numerical calculation based on electromagnetic theory, the combination of the two coupled field analysis. The use of electromagnetic field analysis process calculated the required variables, on behalf of the entering acoustic-structure coupled field analysis, the resultant sound field distribution. The article generally describes the COMSOL finite element modeling and the use of the two modules. This article will not discuss how to optimize electric transducer structure.
