Two equations for description of the pendulum damper
C. Fischer, J. Náprstek
pages 253 - 259, full text

The pendulum damper modelled as a two degree of freedom strongly non-linear auto-parametric system is investigated using two approximate differential systems. Uni-directional harmonic external excitation at the suspension point is considered. Semi-trivial solutions and their stability are analyzed. The thorough analysis of the non-linear system using less simplification than it is used in the paper (N´ prstek & Fischer, 2007) is performed. Both approaches are compared and a conclusions are drawn.
