Bifurcation and chaos of periodicmotions of a single-degree-of-freedom system with piecewise-linearity is studied.

By using the frequency analysis method the periodicmotions and chaotic motions are judged, and the periodic orbits embedded in different chaotic bands are distinguished.
利用频谱分析法对周期运动和混沌运动进行判断，并对嵌于不同混乱带中的周期轨道进行区分。

In allusion to the characteristic that Geocentric motion is piled up by several periodicmotions, the spectral analysis by wavelet and ar were discussed in turn in this paper.
