STUDY ON VIBRATION OF FLUID-FILLED CYLINDRICAL SHELLS WITH RING-STIFFENER USING WAVE PROPAGATION APPROACH

The vibration characteristic of fluid-filled cylindrical shells with ring-stiffeners is studied. Theoretical formulation is established based on the Love's shell theory. The shell eigenvalue governing equation is derived with the consideration of fluid-filled property, using a wave propagation approach. Then the coupled frequency of the cylindrical shell with different boundary conditions is obtained. The present analysis is validated by comparing the results with those in pertinent literatures. The results are presented on the influence of fluid-filled characteristics, stiffening parameters, boundary conditions and the influence of geometrical dimension.
