摘要：

Based on the Love's shell theory and Helmholtz wave equations, the vibration equation about fluid-structure coupling with internal and external flow field is deduced. The dispersion characteristics of propagation waves in FG cylindrical shell with flow field is studied and compared with the isotropic cylindrical shell. The research shows that in the frequency band the mainly motion components are tension and torsion, the change of material of FG cylindrical shell has great influence on phase velocity of the propagation waves. And the effect to torsion is more obvious than tension. However it is less important to the phase velocity of bending wave. This paper can provide reference for studying wave-motion characteristics of non-pressure shell with new style composite material.
