摘　　要：The wave propagation approach is presented to research the active vibration control of two-beam structures.Considering the continuity of the generalized displacement and the equilibrium of the generalized force at the discontinuity,the wave reflection and transmission coefficients are calculated.Wave control is applied somewhere upstream or downstream to two-beam structures.Vibrations of two coupled beams per unit disturbance are investigated.The results show that wave control is efficient,and the influence of the thickness ratio of two-beam structures on control location is discussed.The wave propagation approach is presented to research the active vibration control of two-beam structures. Considering the continuity of the generalized displacement and the equilibrium of the generalized force at the discontinuity, the wave reflection and transmission coefficients are calculated. Wave control is applied somewhere upstream or downstream to two-beam structures. Vibrations of two coupled beams per unit disturbance are investi- gated. The results show that wave control is efficient, and the influence of the thickness ratio of two-beam structures on control location is discussed.
