| 摘 要： | 以一无限长弹性充液圆柱壳为研究对象，分别用Ｆｌｕｇｇｅ壳体理论与Ｈｅｌｍｈｏｌｔｚ方程分析管壁结构波运动和管内声场，通过管壁内表面的运动协调条件，建立此耦合系统的运动微分方程。分析了耦合波的传播特点。重点讨论在自由传播波作用时，由壳体中各内力传播的功率流，从能量角度分析了各种波的传播特点。

| Abstract: | An infinite cylindrical elastic shell filled with fluid is studied.The simple harmonic motion of the shell and the pressure in the contained fluid are described by the Flgge shell equation and Helmholtz equation,respectively. According to the radical velocity at the shell wall between the fluid and the shell,the equations of motion of this coupled system are obtained.The dispersion behaviour of free waves is investigated.An equation which determines the vibrational power flow carried by different internal force is derived.The characteristics of propagating waves are discussed from the point of view of energy. |
