综合考虑轻微磨损故障和裂纹故障等因素,建立含故障的直齿轮副的非线性动力学模型,并利用4~5阶变步长Runge-Kutta法对含故障的直齿轮模型的动力学方程进行数值求解;得到了单级齿轮系统在无故障、轻微磨损故障和裂纹故障状态下系统的分岔图、相图和Poincaré映射图;研究了齿轮系统在无故障和故障时的动力学行为,研究结果为齿轮系统的故障诊断、动态设计和安全运行等提供了理论参考。
The nonlinear dynamics model for a spur gear pair system is established where the mild wear and crack faults are considered. The nonlinear dynamics equations with faults are solved by employing 4~5 order variable step size Runge-Kutta method. The bifurcation diagrams, phase portraits and Poincaré maps of the single-stage gear system under the condition of no fault, mild wear fault and crack fault are obtained to research the nonlinear dynamics characteristic of system. The dynamics behaviors of gear system in fault-free and fault are studied. The conclusions provide theoretical reference for fault diagnosis, dynamic design and safe operation of gear system.
