摘要基于Flügge壳体振动理论，将改进精细传递矩阵法应用于水下加筋柱壳声辐射问题的求解。通过应用加法定理和增量存储，改进非齐次项求解方法，构造了加筋圆柱壳的辐射噪声改进精细传递矩阵法。分析了边界条件、结构损耗因子、流体介质以及壳体厚度对加筋圆柱结构声辐射的影响。研究表明，当边界条件从自由、简支到刚固，结构对外辐射声压逐渐降低；随着结构损耗因子的增大，结构对外辐射声压大体上逐渐降低。

Abstract：Based on Flügge shell theory, improved precise transfer matrix method (IPTMM) was applied to solution of acoustic radiation for stiffened cylindrical shell. According to the techniques of addition theorem and increment storage, calculation of inhomogeneous was improved. Then, improved precise transfer matrix method was obtained. The effects of different ends boundary condition, structural damping, fluid medium and shell thickness were presented. The results show that when the boundary conditions from freedom supported and simply supported to rigidly fixed, external radiation acoustic pressure of structure gradually reduces. With the increasing of structural damping, external radiation acoustic pressure of structure gradually reduces.
