On the critical damping in multi-degree-of-freedom systems

摘要

The concept of criticality in viscously damped multi-degree-of-freedom systems is discussed. A necessary and sufficient condition for critical damping is presented. The fundamental physical basis is the same as in Beskos and Boley [ASME J. Appl. Mech. 47 (1980) 627], but numerical convenience is enhanced. (C) 2002 Elsevier Science Ltd. All rights reserved.
