Vibrations of rotating thin cylindrical panels

Abstract

In this paper, the vibrations of rotating thin cylindrical panels are investigated. The differential equations of motion, which take into account the effects of centrifugal, Coriolis and initial tension, are formulated using Love's first approximation theory for a thin shell theory. The analysis is carried out using closed-form solutions for simply supported boundary conditions and the eigensolutions are obtained using the Newton-Raphson method. Parametric studies are made on cylindrical panels which rotate about their horizontal axes and are of the rectangular and square planform types. The results obtained indicate that the bifurcations of natural frequencies are similar to those for a rotating cylindrical shell. The analysis is validated against results available in the literature. © 1995.
