| 中文摘要: |
| 本文用边界元的方法计算了阵形任意的水声发射换能器共形阵的辐射声场。在详细研究了边界元方法基本理论的基础上,采用Pro／ENGINEER,软件与ANSYS软件相结合来建立换能器阵的边界元模型,再用SYSNOISE软件计算其辐射声场和辐射阻抗。这种声场计算方法可用于发射换能器阵设计阶段对设计结果进行预报。 |
| 英文摘要: |
| The boundary element method is used to calculate the radiated acoustic field of a complicated conformal array of underwater acoustic projecting transducers. At first, the fundamental theory of the boundary element method is carefully studied. The commercial softwares Pro/ENGINEER and ANSYS are then used to build up the boundary element model of the conformal array, and SYSNOISE is used to calculate the acoustic radiated field and the radiation impedance of the array. The technique presented in this paper can be used to predict the performance of a projecting transducer array at the stage of preliminary design. |
