Abstract

Abstract

A synthetic technology for substructure test modeling was developed based on the finite element model updating theory and the modal synthesis method. During the substructure model updating, the fixed interface component modal synthesis method was adopted to reduce the substructure model, improve the computational efficiency and thereby promote the overall efficiency of the substructure test modeling. The steps of the design parameter method in model updating and the corresponding formulas based on the reduced model were given. With a launch vehicle model as the example, and by means of the secondary development of ANSYS, the present method gets verification of effectiveness.
