Since the damping matrix in the motion equation of damped blade is no longer decoupled as Rayleigh damping, so the complex mode theory is introduced in this paper to overcome the difficulty.
A mathematic model of the linear damped oscillation of swing with parameter exciting is presented. The theoretical analysis and numerical simulation for the motion behavior of swing is done.
