The authors propose 'Multiple Component Mode Synthesis Method' for analyzing the vibration of complex mechanical structures. This method is carried out as follows. A structure is divided into some first divided components. Each first divided component is subdivided into some second divided ones. Repeating this process n times, the structure is divided into n-th divided components at last. The natural mode of each (n-1)-th divide component is analyzed using the natural modes of the n-th divided ones by the technique of the ordinary component mode synthesis method. Next, the natural modes of each (n-2)-th divided component is analyzed with the natural modes of the (n-1)-th divided ones. After repeating this process, the vibration of a total structure is analyzed. By the present method, a structure can be analyzed with less memory size of computer than either the ordinary component mode synthesis method or the finite element method. As a numerical example a plate is analyzed by the present method and the results are compared with those by experiment and by the finite element method.
