Aerospace Structures Technology Damping Design Guide. Volume 1. Technology Review

Abstract

This volume contains a summary of the current technology used in the application of viscoelastic damping to primarily aerospace structures. The topics covered include the fundamentals of damping, the level of the damping present in metals, composites and aerospace structures made from these materials, and methods for measuring this damping; the fundamentals of viscoelastic damping materials, the test methods used to obtain the damping material data and the method of presenting these data; the basic viscoelastic damping theory for the free and constrained layer damping design and for tuned dampers, and the finite element analysis used in the design of more complex viscoelastic damping applications. A brief review of the classical methods for predicting the vibration response of aircraft type structures is also included together with a discussion of the effect of damping on the noise transmission loss of these types of aircraft structures.
