摘　　要：综合考虑齿轮时变啮合刚度及齿轮误差等内部激励的影响,建立了单对齿轮扭转振动物理模型,采用龙哥库塔法进行求解,得到了齿轮节点位移。分析齿轮几何参数对齿轮啮合的振动噪声的影响,并采用修正Kato公式法对振动产生的噪声进行了定量计算。结果表明该方法可以较好地对齿轮振动所产生的噪声进行定量计算,为齿轮系统的降噪设计奠定了基础。The dynamic response of a single pair of gears was analyzed in consideration of the time varying mesh stiffness,gear errors,transmission errors.The dynamic response model was set up by using torsional vibration of the physical model.The time varying mesh stiffness is calculated by substituting the variance of the contact line length,when the unit contact line length of the mesh stiffness is constant.Then the node displacement of the gear was solved by using the Runge-Kutta method.The influence of geometry parameters of the gear on the vibration and noise of gear meshing was analyzed,and the noise due to vibration is quantitative calculated by using Kato method.It is shown that this method is a good ideal method for quantitative calculating the noise due to gear vibration.It gives examples to provide basis for low noise design and noise-decreasing of gear system.
