چکیده
This paper deals with large amplitude oscillation of a nonlinear pendulum attached to a rotating structure. The concept of amplitude-frequency formulation and He’s energy balance method is briefly introduced, and its application for the rotational pendulum system is studied Accuracy and validity of the proposed techniques are then verified by comparing the numerical results obtained based on the HAFF, HEBM and exact integration method.
