Research on Bifurcation and Chaos of 3-DOF Gear Transmission System

  • 摘要: 为研究齿轮传动系统中齿侧间隙等非线性因素对系统振动特性的影响, 综合考虑齿侧间隙、时变啮合刚度、综合啮合误差和轴承纵向响应, 建立了三自由度单级直齿轮副传动系统的扭转振动非线性动力学模型;采用变步长4-5阶Runge-kutta法, 对系统运动的状态方程进行了数值求解;并构建了系统的Poincaré截面, 得到了系统的分岔图。结合系统最大Lyapunov指数谱、Poincaré映射图及FFT频谱图, 分析了系统在激励频率变化时的动力学特性, 发现系统在不同激励频率下会发生Hopf分岔、鞍结分岔及倍化分岔, 给出了系统的分岔值, 分别得到了系统经Hopf分岔和鞍结分岔通向混沌运动的两种过程。
