Identification and prediction of Frame Structure Dynamics by Spatial Matrix identification Method

摘要

This paper presents the results of using an experimental spatial matrix identification method to predict the dynamics f a frame structure under various boundary conditions. The single-input-multiple-output frequency response functions (FRFs) of the test structure Under the free-free boundary condition are measured by hammer testing. Using the FRFs, A set of spatial matrices is constructed in order to represent the structural dynamic characteristics of the system by the new method.
