Constrained-Layer Damping of Torsional Vibration of Thin-Walled Tubes
Keyword(s):
Abstract In this paper, we take up the problem of damping torsional vibration of thin-walled tubes with closed sections. Assuming that the deformation obeys the Saint-Venant hypotheses, we develop a model suitable for predicting the complex stiffness per unit length in tubes with constrained viscoelastic layers over part or all of their perimeter. For some basic cross-sectional shapes, we solve the warping problem and thence obtain closed-form expressions for the complex stiffness per unit length. Finally, we provide some guidelines for the design of tubes with high damping in torsion.
