Aiming at consecutive dynamic vibration absorber and plate coupling system, the absorption ability of dynamic vibration absorber with consecutive parameters is analyzed, which is based on the theory of power flow together with the finite element method. The simulation results and experiment data show that the composite beam has advantages in high energy dissipation and wide absorption bandwidth. To develop absorption ability of the dynamic vibration absorber, optimization is excluded in ANSYS optimization mode. The results show that the absorption ability has improved greatly in a wide frequency range after the optimization and the optimization method is proved to be accurate.
