本文研究了轴对称波在充压正交各向异性加筋管内的传播。绘制了这些波的频散曲线，并确定了通过壳体或流体传递能量的波。同时考虑了内压和轴向薄膜应力的影响。结果发现，正压不会导致未编织橡胶管变硬。流体载荷引起的流体主导的波的速度的变化很大，但只有很小的变化，在壳体的轴向波。
The axisymmetric waves propagating within a pressurized, fluid-filled orthotropically stiffened tube are investigated. The dispersion curves for these waves are plotted and the waves transferring energy through the shell or fluid are identified. The effect of internal pressurization and axial membrane stress is also considered. It is found that positive pressurization did not cause stiffening of unbraided rubber tubes. Fluid loading caused large changes to the fluid dominated wave speed but only small changes to the axial wave in the shell.
