The dynamic response of a beam-tip mass-pendulum system subjected to a sinusoidal excitation is investigated. A simple pendulum mounted to a tip mass of a beam is used as a vibration absorber. The nonlinear equations of motion are developed to investigate the autoparametric interaction between the first two modes of the system. The nonlinear terms appear due to the curvature of the beam and coupling effect between beam and pendulum. It is shown theoretically, when the external resonance condition of Ω = ω-b$/ with the primary resonance condition of ω-b$/ =2ω-p$/ are satisfied, complete energy transfer occurs between the two modes.
