An efficient method for free vibration analysis of rotating truncated conical shells

This paper proposes a discrete singular convolution method for the free vibration analysis of rotating conical shells. A regularized Shannon's delta kernel is selected as the singular convolution to illustrate the present algorithm. Frequency parameters of the forward modes are obtained for different types of boundary conditions, rotating velocity and geometric parameters. The present results compare well with numerical data available in the literature. Numerical experiments reveal that the present approach is accurate, efficient and reliable for vibration analysis of conical shells.
