Vibration Analysis of Curved Skin-Stringer Structures Having Tuned Elastomeric Dampers.
Abstract
The steady state vibration response of curved skin-stringer structure is analyzed through the application of transfer matrix techniques. Previous transfer matrix analyses of similar structures are improved through the development of a technique for generating the transfer matrix for a curved panel directly from the matrix differential equation, representing eight first order linear differential equations, for an appropriate shell theory. In addition, the effects of stringer stretching and finite stringer width are analyzed. Specifically, the analysis is demonstrated on a structure consisting of a row of five cylindrically curved panels with constant radius of curvature, stiffened by stringers parallel to the generators and simply supported by frames normal to the stringers at the edges.
