A novel model comprising of a vibration absorber and an axially loaded beam bridge is studied from a vibratory power flow viewpoint to examine its dynamical behavior and power flow characteristics.The vibration absorber incorporates a lumped mass linked by a pair of inclined elastic springs that are capable of resisting both tension and compression(called SD absorber).And the beam bridge is subiected to an infinite series of regularly spaced concentrated moving loads whose distance between the neighbor ones is the length of the bridge.
