摘要
文章以某型号曲轴随动磨床液体静压电主轴和砂轮架体为研究对象,运用软件SolidWorks对液体静压电主轴和砂轮架体进行几何建模,通过有限元分析软件ANSYS Workbench对液体静压电主轴和砂轮架体进行静动态特性分析,进而计算液体静压电主轴和砂轮架体在磨削力作用下的静力变形状况、在自由振动情况下的多阶固有频率和振型状况以及在激振力作用下的动力响应特征。分析结果表明砂轮架体及电主轴的设计满足技术要求。砂轮架体及电主轴的静动态特性分析对改进曲轴随动磨床结构、提高曲轴随动磨床的磨削效率、规避工作频率引起的振动、提高磨床的表面磨削质量等均具有重要的意义。
In this paper,the hydrostatic spindle and grinding wheel frame of a certain type crankshaft follow-up grinding machine are studied,using SolidWorks software to establish the geometric model of hydrostatic spindle and grinding wheel frame,then use the finite element analysis software ANSYS Workbench to analysis the static and dynamic characteristics of the hydrostatic spindle and the grinding wheel frame.The static deformation state under the action of grinding force,the natural frequencies and vibration modes under free vibration,and the dynamic response characteristics under the action of excited force of the hydrostatic spindle and grinding wheel frame are calculated. The analysis results show that the design of grinding wheel frame and motorized spindle meets the technical requirements. Static and dynamic characteristics analysis of the grinding wheel frame and the motorized spindle are of great significance for improving the structure of crankshaft follow-up grinding machine,improving the grinding efficiency of crankshaft follow-up grinding machine,avoiding vibration caused by working frequency,improving the surface grinding quality of grinder and so on.
