-
摘要: 本文应用Hamilton原理、Huygens原理和Green函数方法导出了环肋圆柱壳在流场中辐射声压的解析公式,可用来计算壳体表面、近场和远场的声压。Abstract: In this paper,analytical for mularions of radiated sound pressure of ring-stiffened cylindrical shells in fluid medium are derived by means of Hamilton's principle Huygens' principle and Green function.These formulations Can be used to compute the sound pressure of the shell's surface nearfield and farfield.
