Vibration analysis for a coupled beam-sdof system by using the recurrence equation method

This paper presents the vibration analysis of a coupled system composed of a beam and a single-degree-of-freedom (sdof) system. The harmonic responses of this kind of system are formulated by means of the recurrence equation method. In addition, the natural characteristics of the system are also analyzed. Numerical examples of the undamped system are given and compared with the published results, and an excellent correlation shows that the study work in this paper is correct.
