基于界面主从位移控制的频响子结构方法
The substructure FRF synthesis based on the master-slave displacement control principle on interfaces
摘要
Abstract
In substructure response analysis of complex engineering structures,the frequency response function (FRF) of each substructure is often obtained by different departments,and the FRF may be associated with different coordinate,or some substructures have symmetry between each other.In these cases,we need to rotate and mirror each substructure FRF before its coupling processes.Moreover,when coupling substructures,the coupling points of these substructures are likely to be incompatible at their interfaces,and these interfaces need to be processed to ensure the deformation compatibility.So an improved method of the substructure FRF synthesis is developed which is based on the master-slave displacement control principle and can consider both substructure rotating and mirroring and substructure flexibility on interfaces.It can greatly improve the computational efficiency.When the master-slave control matrix is an identity matrix especially,the improved formula can degenerate into the traditional formula of substructure FRF synthesis.Numerical examples demonstrate the validity and effectiveness of the proposed method.关键词
