| 摘 要： | 考虑轴承的支承刚度,建立了丝杠在两端弹性支承条件下纵向振动、扭转振动和横向振动的频率方程。对于纵向振动和扭转振动,分析了轴承支承刚度对其振动频率的影响。对于丝杠的横向振动,采用Timoshenko模型,综合考虑了转动惯量、涡动效应和预拉伸力对丝杠振动的影响,分析了轴承支承刚度、旋转速度和预拉伸力对丝杠横向振动频率的影响,分析了丝杠在启动过程中的共振,为回转系统减少或消除共振提供了理论依据。

| Abstract: | In this article,the bearing stiffness is taken into account,the frequency equation of longitudinal vibration,torsional vibration and lateral vibration of the screw is derived.To the screw's longitudinal and torsional vibration,the effect of the bearing stiffness on the vibration frequency is analyzed.To the screw's lateral vibration,the model of Timoshenko is used to synthetically consider the effects of rotatory inertia,eddy effect and pre-tension force on the lateral vibration,analyze the effects of the b... |
