摘要：为了求解复杂结构体下的声场分布，采用ANSYS软件建立了声场结构二维混合有限元模型，给出了ANSYS软件中混合模型的建模方法，通过在结构体四周设置结构体与空气耦合单元，将结构模型因受力发生形变而产生的噪声声压耦合到空气中，实现了混合声场模型的求解。模型求解结果表明，该模型能很好地解决声场与结构场的耦合问题。

Abstract: Aiming at resolving the finite element model of the sound and structure, ANSYS software was used to set up compound model of structure and sonic field. The modeling method through ANSYS was introduced. Through the coupling elements around the structure, compounding the sound pressure produced by deformation of the structure model in the air elements, the compound sonicfield model was realized. The analysis results indicate that the model may resolve the compound problem of structure and sonic field accurately.
