摘　　要：利用有限元法和边界元法相结合的方式,对I类凹筒结构弯张水声换能器进行了全面的分析。具体方法是借助于网格模型数据和计算结果数据共享的思想,将有限元法的结构、振动分析优势同边界元法的声场分析优势互补起来。相关试验表明,这种相结合的分析方式更全面、准确,是对水声换能器性能分析和优化设计手段的有益完善。The class I flextensional underwater transducer with the barrel-stave structure has been analyzed thoroughly by the way of combining the finite element method（FEM） and the boundary element method（BEM）.Its essential idea has been obtained from the data sharing of the mesh models and the solving results,and so the complementary advantages between the structure or vibration analysis of FEM and the acoustic field analysis of BEM have been achieved.The corresponding tests showed that the combined analysis method could provide an all-sided and accurate insight for the underwater transducers,and it will perfect the way of analyzing and optimizing the underwater transducer.
