Frequency characteristics of a rotating truncated circular layered conicalshell

This paper presents a method to study the free vibration of a rotating trun cated circular layered conical shell with simply-supported boundary conditi ons. Based on the Love first approximation theory and Galerkin procedure, a nd taking into account the influences of centrifugal and Coriolis accelerat ions and the effects of initial hoop tension, the frequency characteristics are obtained for various geometric properties, vibrational modes and diffe rent rotating speeds. The effect of cone angle on frequency characteristics is also discussed in details. Comparisons with published results available in the literature indicate that the present method is reliable and applica ble. (C) 2000 Elsevier Science Ltd. All rights reserved.
