A Semi-analytical Method,a nonlinear system has a periodic motion with a period of ., then such a periodic motion can be expressed by discrete points through discrete mappings of continuous corresponding systems. The method is presented through the following theorem. From Luo , we have the following theorem.

Discretization,period-1 and period-m motions will be discussed and the corresponding stability and bifurcation criteria will be presented. The finite Fourier series of periodic motions will be discussed from the corresponding discrete nodes.

Period-1 Motion to Chaos,esented. The harmonic frequency-amplitude characteristics are presented for vibration reduction and energy harvesting, which can help one better understand nonlinear dynamics of the tuned mass damper systems. Period-1, period-2 and period-4 motions are illustrated through phase trajectories and harmonic amplitude spectrum.
