间接耦合机械结构之间的耦合损耗因子

本文利用双端口法推导了强耦合或相互处于振动波近场范围内的机械结构中间接耦合结构之间的耦合损耗因子的计算公式。用考虑了间接耦合损耗因子的修正统计能量分析的能量平衡方程预测了转动机械结构响应，预测结果与实验测量结果之间的一致性优于用经典统计能量分析法预测的振动响应。

Coupling loss factors between indirectly coupled machinery structures

The formulae for cajculating coupling loss factors between indirectly coupled structures of Which the coupling is strong or in the near field of the vibrating wave of the structures each other are derived by using two port method. The responses of the rotating machinery structures are predicted using the modified SEA balance equations with the indirect coupling loss factors and the agreement between the predicted and measured responses is better than those predicted by using the classical SEA equations.
