Abstract:

This paper presents the optimal design of a tunable nonlinear absorber. A nonlinear dynamic model is established based on the Hamilton principle of the minimum potential energy. The response equation of the two-DOF (degree of freedom) tunable nonlinear absorber is solved by the average method and the stability of the system is analyzed., It is shown that with the optimized parameters, the amplitude of the vibration is reduced.
