研究了充满流体的无限弹性圆柱壳的振动功率流特性。用菲格壳方程和亥姆霍兹方程分别描述了壳体的简谐运动和流体中的压力场。利用壳体与流体的耦合，得到了该系统的振动方程。利用傅里叶变换及其逆变换，研究了简谐线性分布驱动力下的耦合系统输入功率。讨论了不同壳体内力和所含流体所携带的功率流沿壳体的传递。
The characteristics of vibrational power flow in an infinite elastic cylindrical shell filled withfluid are investigated. The simple harmonic motion of shell and the Pressure field in the contained fluidare described by the FIugge shell equations and the Helmholtz equation respectively. The vibrationalequation of this system is obtained by using the coupling of shell and fluid. By using the Fouriertransform and its inverse transform, the input power into this coupled system under a simple harmonic,linearly distributed driving force is studied. Along the shell, the transmission of the power flow carriedby different shell internal forces and by the contained fluid are discussed.
