Aerospace Structures Technology Damping Design Guide. Volume 2. Design Guide

Abstract : This volume represents the basic design guide for the application of viscoelastic damping to primarily aerospace structures. Simplified design equations for the vibration response of structures and for the free layer, constrained layer and tuned damper damping applications are presented. These equations are to be used with the damping material data in Volume III to develop the required design. For more complex structures, the above analysis should be supplemented by finite element analysis also discussed in this volume. The other topics included in this volume are the factors contributing to vibration problems in aerospace type structures including a summary of the vibration environments; a discussion of the design approach including when each of the three damping treatments should be used; examples on the use of the design equations, design examples and case histories of successful applications viscoelastic damping, and a discussion of other practical design considerations; a summary of the damping in aerospace materials and structures; and finally, a summary of material properties for typical aerospace metals and composite materials. Keywords: structural vibration response equations, viscoelastic damping design approach, viscoelastic damping design equations, example problems, viscoelastic damping design applications, case histories, other design considerations, damping in composites, damping in metals, damping in aerospace structures, metal material properties, conversion tables.
