摘要:

为研究非圆行星齿轮系统非线性动力学特性,基于非圆行星齿轮各构件运动关系建立非圆行星齿轮传动系统;考虑时变啮合刚度、齿侧间隙、啮合阻尼、激励频率等关键非线性因素,构建非圆行星齿轮非线性动力学模型;运用分岔图、相图和时域图等表征方法定量研究系统动态行为,揭示了不同参数条件下对系统振动响应的影响机制。结果表明,偏心率、啮合阻尼和激励频率变化的情况下系统表现出丰富的动力学行为;大阻尼和高激励频率有利于非圆行星齿轮系统的运行稳定;偏心率可调控太阳轮性能。

Abstract:

To investigate the nonlinear dynamics behavior of non-circular planetary gear systems, a non-circular planetary gear transmission system was first developed based on the relative motion relationships among system components. Subsequently, a nonlinear dynamics model was established by incorporating critical nonlinear factors including time-varying mesh stiffness, backlash, meshing damping, and excitation frequency. The dynamics characteristics were quantitatively analyzed through bifurcation diagrams, phase portraits, and time-domain waveforms to elucidate the influence mechanism of various parameters on system vibration response. The results show that the system exhibits complex dynamics behaviors under variations in eccentricity, meshing damping, and excitation frequency. Higher damping coefficients and elevated excitation frequencies are found to enhance system stability, while eccentricity is identified as an effective parameter for sun gear performance modulation.

Key words: non-circular gear, planetary gear transmission system, nonlinear dynamics, bifurcation and chaos
