【摘要】 研究了单级啮合故障齿轮传动系统的多自由度动力学模型,建立了包含驱动机、负载、联轴器和轴承等多质量系统的运动学微分方程;理论上研究了无故障和裂纹故障激励下的系统响应特性和故障信号波形特征,研究了系统参数啮合刚度对系统响应特性的影响。更多还原

【Abstract】 The paper studies a multi-DOF dynamic model of one-stage gearbox system.Motion equations of lumped parameters including motor,load,flexible couplings and bearings are built.Vibration responses of both healthy gearbox and gearbox with crack fault are studied in theory.Fault signal waveform feature and the effect of system parameter,for example the meshing stiffness on system response are outlined.更多还原
