The problem of suppression of supersonic flutter of laminated composite panel using dynamic absorber device was investigated.The interaction forces between the panel and the dynamic absorber device were expressed as the functions of relative displacement and velocity of the panel and the absorber.Based on the von-Karman nonlinear deflection panel theory and the 3rd-order nonlinear piston theory

the equations of motion of the panel and the absorber were established according to the Hamilton principle and the Newton second law of motion.Then the assumed modal method was adopted in the discrete procedure

and the numerical simulation was conducted.The coordinate of the absorber was optimized.The simulation results indicate that the critical flutter dynamic pressure can be enhanced by 51.7% under certain parameters of the absorber

and the amplitude of the limit cycle oscillation can also be suppressed.
