| 摘要: |
| 以某型号磨床砂轮架主轴为研究对象,利用Solidworks对其进行三维建模,导入ANSYS软件进行模态分析,得到其固有频率、振型和临界转速,并对所得的数据进行了科学分析.分析结果表明:主轴结构合理,可以保证加工精度;同时得到主轴变形最剧烈以及可能出现主轴疲劳断裂的位置,为下一步的优化设计和精度控制提供了理论依据. |

| Abstract: |
| The object of research is to a certain type grinding wheel spindle for which a 3D model of the spindle is established by SolidWorks software and ANSYS software is imported for model analysis.Natural frequency,vibration type and critical speed of the spindle model are obtained and the resulting data are scientifically analyzed.The results show that the spindle structure is reasonable,the machining accuracy can be ensured and the position where the most severe deformation and the main shaft fatigue fracture may occur can be found out,which also provide the theoretical basis for further optimization design and precision control. |
