A method is presented to analyze the forced vibration of a complex mechanical structure by using the natural modes of its components. The structure is divided into some components. All components are classified into master components and branch ones. The natural modes of each component are determined separately by the finite element method. The natural modes of all components are synthesized to form generalized system coordinates. The equation of motion under these system coordinates is solved to know the natural frequencies and the natural modes under these system coordinates. Using these natural modes, the response of the forced vibration is solved by the technique of the modal analysis. The forced vibration of three specimens is analyzed by the present method. On the other hand, the forced vibrations of these specimens are measured experimentally under the harmonic exciting force to get the compliances. The calculative results are compared with the experimental ones to check up on the accuracy of the calculation and availability of the proposed method.
