A Fixed-loaded Interface Component Mode Synthesis Method for Dynamic Analysis of a Folding Wing

Abstract

A fixed-loaded interface component mode synthesis method is presented for carrying out a dynamic analysis for a folding wing. The present method has the advantages of the fixed interface method and loaded interface method, in which the effects of the elastic and inertia force at interfaces are included and the size of dynamic problem is highly reduced through elimination of interface coordinates. It is shown in the paper that the present method is able to predict the natural frequency accurately. Further, it can be integrated with the multibody dynamic code to perform the transient dynamic analysis during the morphing process.
