| 摘 要： | 本文以滚动轴承内圈局部故障为研究对象,建立三自由度分段非线性故障碰撞模型,通过在故障缺陷的碰撞面处建立Poincaré映射,研究当故障系统随频率增加时,由于滚动体与内圈缺陷的碰撞冲击而出现的Neimark-Sacker分岔等非线性行为,有助于揭示故障碰撞机理,为设备的减振降噪提供理论依据.

| Abstract: | Piecewise non-smooth model of three-degree-of-freedom rolling bearing system with fatult in inner ring was established by the method of the nonlinear theory.The Neimark-Sacker Bifurcation of bearing system was first studied in this paper.The numerical method was used to further reveal the bifurcations and chaos of bearing system through establishing the Poincaré mapping on the collision plane.With the increase of rotating frequency,the system has experienced the nonlinear dynamical behaviors of classical Neimark-Sacker bifurcations.The study of bifurcation and chaos of the fault bearing system provides reliable basis for the design and fault diagnosis and provides theoretical guidance and technical support for the actual design in the safe and stable operation of large high-speed rotating machinery. |
