Dynamic characteristics of PX single loop gear train considering weak nonlinear factors of intertooth system

Due to the non-linear factors of single loop gear system and inter-tooth system, is sometimes difficult establish an accurate nonlinear dynamic model, which leads large deviation between characteristics actual situation. According structural mechanism factors, bond graph power junction with switching adopted. This method used model respectively. On this basis, amplitude-phase-frequency PX systems are obtained by numerical simulation analysis. Eventually, stability judged based on characteristic index. The study shows that type unsteady in state. In addition, it concluded when whole unstable, its module also has same unstability.
