Shell Mode Coupling

Abstract

This report describes a parametric study of stiffened cones and cylinders to analytically determine the effects of a longitudinal steady state driving force on the radial velocity of axially symmetric shells. The lumped-mass technique is utilized to predict the natural frequencies, mode shapes and impedances (point and transfer) for eight cases. Although the natural frequencies are not too sensitive to changes in shell thick ness and frame area, the transfer impedances (hence radial velocities) vary significantly for the cases studies.
