| 摘 要： | 针对滚珠丝杠副在外力作用下容易产生变形、振动等特点,以滚珠丝杠副为研究对象,应用Solid Works软件建立滚珠丝杠副三维装配体模型,简化后导入到ANSYS Workbench软件中,在对模型设置约束条件和划分网格后,对其进行模态分析,结果表明:滚珠丝杠副的前六阶振型都为弯曲变形振动,在第六阶固有频率下,丝杠正中位置振动幅度最大,为滚珠丝杠副的薄弱环节。

| Abstract: | Aiming at the characteristics of easy deformation and vibration of ball screw under the action of external force, the three-dimensional assembly model of ball screw is established by using SolidWorks software, and then it is simplified into ANSYS Workbench software. After setting the constraint conditions and meshing the model, the modal analysis is carried out to obtain the first six natural frequencies and vibration modes of ball screw. The results show that the first six vibration modes of ball screw are bending deformation, and the middle position''s vibration amplitude of the screw is the largest in the natural frequency of the sixth order, which is the weak link of ball screw. |
