Experimental Investigation of Nonlinear Vibration Absorbers Available to Purchase

An experimental investigation of the performance of nonlinear vibration absorbers on nonlinear systems was performed. The results verify the previous analytical findings of the authors. Initially, for low excitation, the nonlinear absorber gives better results than the nonlinear case. However as the forcing level is increased, the system response undergoes a series of Hopf bifurcations leading to chaotic behavior and poor absorption of the vibrations.
