Model and nonlinear characteristic analysis of the overrunning clutch-single pair gear system

建立了考虑间隙、时变啮合刚度、综合传动误差的超越离合-单对齿轮副系统的非线性动力学模型,并给出评价该系统分岔、振动、载荷以及碰撞特性的综合性能指标。通过对系统分岔与混沌特性的研究,揭示了该系统响应随着激励频率变化时所经历的倍周期分岔、准周期分岔、阵发分岔等几类通向混沌分岔路径共存的复杂分岔路径,体现了超越离合-单对齿轮副系统非线性动力学行为的复杂性态;通过对参数影响趋势的研究,总结了有关超越离合-单对齿轮副系统的一般性动态设计准则。

By taking clearance, time-varying meshing stiffness and transmission error into account, a nonlinear dynamic model of the overrunning clutch-single pair gear system （ OC-SPGS ） has been established. Comprehensive performance indices about the performance of the bifurcation, vibration, load and contact have been given. Research on bifurcation and chaotic features reveals complex bifurcation roads with excitation frequency changes, which comprise the period-doubling bifurcation, quasi-periodic bifurcation and intermittency bifurcation. Additionally, general dynamic design criteria for OC-SPGS have been summarized based on research on the parameters＇ influence.
