A component mode synthesis method capable of estimating vibration responses efficiently in a high-frequency range is presented. In order to analyze the response in a high-frequency range, a high and low order truncatable mode superposition method is incorporated in the reduction process included in both the formulation of component mode synthesis and solving the superimposed global equation of motion. By truncating lower modes, it becomes possible to analyze a system with fewer degrees of freedom than the existing modal reduction methods. Frequency response analyses of several test problems of damped structures are performed and compared with the multipurpose versatile code, MSC/NASTRAN, to demonstrate the efficiency and versatility of the proposed method.
