摘　　要：针对典型的交直交型动车组CRH2车型,推导出其在正弦脉宽调制下的参数方程,并建立一套新的非线性参数模型.通过混沌原理分析了高次谐波的分形情况,并针对典型的牵引变电站,进行了计算和仿真,依托实际录波的数据验证,证实高频谐波能够导致系统谐振,为混沌分析方法拓展了新的应用.Considering typical AC-DC-AC multiple units, CRH2 motor car, in this paper we deduce its parametric equations under sine pulse width modulation, and set up a new nonlinear parameter model. Fractal situation of higher harmonic is analyzed based on chaos theory. Aiming at typical traction substations, calculation and simulation are conducted, and the result is verified based on data from actual wave records, which proves that high-frequency harmonic can lead to system resonance and expands the application of chaos analysis method.
