%X A new model reduction method based on deformation modification is presented for dynamic analysis. Complex structures can be divided into several displacement synchronous parts by analyzing the finite element models based on a synchronistic assumption.The displacement can be approached by an appropriate mode, and the transformation relationship between global displacement and local displacement can be obtained by minimizing Global Strain Energy.The results of examples show the validity of the method.
