摘要
目前相关激励下的统计能量关系实质是在比例相关或互谱密度为实数的相关激励下获得的。本文从分析普通相关激励下的功率流入手,给出相关激励下保守耦合系统统计能量关系的普遍形式。实例表明,文中结论是正确的。
In this paper, based on the theory of power flow and energy distribution between conservativelycoupled oscillators under correlative excitations, the equations of power balance for the osciliators arederived, statistical energy analysis theory for conservatively coupled systems under correlative excita-tions are developed. After the input powers are substituted for the equivalent input powers accordingtraditional SEA, the results can estimate the response of structure to high-frequency wide-bank corre-lation excitations. At the end of the paper, the auther gives an example of structure excited by correla-tive excitation to demonstrate the validity of the results given in this paper.
