Cálculo automático do coeficiente de acoplamento pelo método de Newland

Abstract

ln this work we propose modifications and additions to ''SAP IV – structural Analisys System", to make it possible the single run calculations of the coupling factors for vibrating systems with both weak coupling and internai damping and submited to a broad band spectral density excitation. We presenta theoretical explanation about "SEA – Statistical Energy Analisys'' and some results of research in coupling magnitudes.
