STATISTICAL ENERGY ANALYSIS FOR NON-CONSERVATIVELY COUPLED SYSTEMS UNDER HIGH- FREQUENCY WIDE-BAND CORRELATED EXCITATIONS
相关激励下的统计能量分析法（SEA）研究

In this paper,based on the theory of power flow and energy distribution be-tween non-conservat ively co upled os cillators under correlated excit at ions, the equations ofenergy balance for the oscillators are derived and statistical energy analysis theory for non-conservatively coupled systems under correlated excitations is developed. The results showthat the input power vector is substited by the equivalent one, the symmetrical statisticalenergy parameter matrix is substited by the non-symmetical statistical energy parameter-matrix, then in according to formula of traditional SEA, one can estimate the responsesdstructures to highfrequency wide-band correlated excitation. At the end of paper, theauthor gives two examples of structures excited by correlated excitation to demonstrate thevalidity of the results given in this paper.
