为了提高砂轮主轴的柔度及抗振性,保证其静、动态性能,砂轮架主轴的设计与分析对磨削加工具有重要的现实意义。通过对砂轮架主轴的原理与结构进行分析,以经典磨削理论与有限元理论为基础,借助机械设计、材料力学、理论力学等基本知识,建立了平面磨削模型,根据所建立的磨削模型确定磨削力参数,从而设计出砂轮主轴的具体结构尺寸,并通过有限元软件对其强度与刚度进行分析。结果表明:设计出的砂轮主轴满足强度、刚度要求。研究成果为砂轮主轴的动态特性研究提供一定的基础。

To improve the grinding wheel spindle flexibility and vibration resistance,so as to ensure its static and dynamic performances,the analysis and design for the grinding wheel spindle have important practical significance for grinding operation. Through analyzing the principle and structure of the grinding wheel spindle,on the basis of the classical grinding theory and finite element theory,the plane grinding model was built with the basic knowledge of design of machinery,material mechanics,theoretical mechanics,the grinding force parameters were determined,then the specific sizes of the grinding wheel spindle were designed. Through the finite element software,the strength and stiffness analysis were operated. The results show that the designed grinding wheel spindle is meet the requirements of strength,stiffness. This research provides basis for the study of dynamic characteristics of the grinding wheel spindle.
