本文提出了一种用于多级子结构动力分析的简化动态凝聚方法。与静凝聚方法相比,其主要特点是可以考虑子结构内部自由度的动态影响,且具有和静凝聚方法同样简洁的形式,因而很容易在一般的多级子结构系统上实现。本方法用于自振分析可获得比静凝聚方法精度更高的特征对,用于响应分析可以考虑到高阶响应分量的影响,计算出静凝聚方法无法表现出的动响应。 This paper presents a simplified dynamic aggregation method for dynamic analysis of multi-level substructures. Compared with the static cohesion method, its main feature is that it can consider the dynamic influence of the internal freedom of the substructure, and it has the same concise form as the static coherence method, so it can be easily implemented on a general multi-level substructure system. This method can be used for self-vibration analysis to obtain a feature pair with higher accuracy than static coacervation method. For response analysis, the influence of higher-order response components can be taken into consideration to calculate the dynamic response that the static coacervation method can not exhibit.
