Abstract
A single reference frame is frequently employed to derive equations of motion in structural dynamic analysis. For simple structures like a single beam and a single plate, the method of employing a single reference frame usually provides well convereed and accurate results for equilibrium and modal analyses. However, for structures having more general confieurations such as multibeam structures, use of a single reference frame often results in slow convergence and even erroneous analysis results. In the present study, a modeling method employing multiple reference frames for dynamic equilibrium and modal analyses of rotating structures is presented. The superiority of the proposed modeling method over the single reference frame modeling method is verified with numerical examples. (c) 2007 Elsevier Ltd. All rights reserved.
