【摘要】 研究一无限长充液圆柱壳的自由振动特性，考虑当传播波入射到充液柱壳时，其中插入的管壁接头对入射波的反射与透射情况。发现入射波频率、管壁接头的几何与物理特性对入射波有较大影响。这些结论对于工程实际中控制输液管的振动有参考价值。更多还原

【Abstract】 The dispersion behaviour of free waves in thin walled cylindrical elastic shells filled with fluid is investigated.The transimission of flexural type waves through joint discontinuities in the wall is then considered.Materil stiffness and wave frequency are important factors which are found to strongly influence wave transimission.Its hoped that the analysis will shed some light on practical problems such as the control of coupled wave propagation in fluid filled elastical cylindrical.更多还原
