Analysis of Random Response of Structure with Uncertain Parameters : Combination of Substructure Synthesis Method and Hierarchy Method (Special Issue on Reliability Engineering)

Journal of the Society of Materials Science, Japan, 1995
In this paper, the method to obtain the random response of a structure with uncertain parameters is proposed. The proposed method is a combination of the substructure synthesis method and the hierarchy method. The concept of the proposed method is that the hierarchy equation of each substructure is obtained using the hierachy method, and the hierarchy ...

Multi-Domain Substructure Synthesis with Normalized Interpolation Technique for Non-Matching Interfaces

Applied Sciences, 2023
The dynamic prediction of large spacecraft is a time-consuming process. The impulse-based substructuring (IBS) method is an efficient and accurate method for the dynamic analysis of large-scale structures. The ordinary IBS method couples the substructure

An Enhanced Hybrid-Level Interface-Reduction Method Combined with an Interface Discrimination Algorithm

Mathematics, 2023
This study proposes an interface localizing scheme to enhance the performance of the previous hybrid-level interface-reduction method. The conventional component mode synthesis (CMS) only focuses on interior reduction, while the interface is fully ...
