摘　　要：鉴于齿轮传动系统非线性动力学模型的复杂性及参数的多样性,采用全局灵敏度分析方法,研究齿轮动力学模型参数及各参数间的耦合对其动态传递误差和动态啮合力的影响。结果表明,齿侧间隙和啮合刚度是影响齿轮动态传动精度的主要因素,啮合刚度、啮合阻尼和支撑阻尼的相互耦合对齿轮动态啮合力有显著影响,齿轮传动稳定性主要取决于啮合刚度和支撑阻尼。这可为高性能齿轮箱的动力学设计与制造提供指导。Considering the complex structure and diverse parameters of nonlinear dynamic model of gears,the global sensitivity analysis method is adopted to investigate the influence of the model parameters on the dynamic transmission error and dynamic meshing force.The results show that the transmission accuracy is mainly determined by the backlash and meshing stiffness.The meshing stiffness,meshing damping and support damping are mutually coupled,which influences significantly the dynamic meshing force,and the stability of gear transmission is very sensitive to the meshing stiffness and support damping.This can provide referece for engineers to design and manufacture of high performance gearbox.
