摘要
从统计能量分析能量平衡方程式出发，建立了确定多耦合系统ＳＥＡ综合参数的理论及实验方法，此方法既解决了复杂工程结构参数确定难的问题，又能从ＳＥＡ综合参数中解得分立参数损耗因子和耦合损耗因子。为ＳＥＡ法的应用开辟了一条新途径。以加筋板为例，对上述方法进行了验证。
The theory and experiment method which determine the SEA synthetic Parameters of complexcoupling system are established from the SEA energy balance equation.This method not only solves thedifficult problem in complicated engineering structure,but also obtains the separate parameters(lossfactor and coupling loss factor)from SEA synthetic parameters.Thus,a new way of the applicationof SEA method is brought forth and the above method is tested by the ribbed panel.
