摘　　要：为了在设计阶段对高压辊磨机机架进行校核与优化,对辊磨机的机架进行静力学与模态分析,根据仿真计算结果分析辊磨机机架的刚度特性,得出辊轴轴线偏移量。结果表明,辊磨机机架刚度足够,辊轴轴线偏移量极小,满足设计要求。采用有限元分析方法可以在设计阶段对辊磨机的刚度特性进行比较准确的计算,对辊磨机机架的设计以及调心轴承的选择提供有效依据。In order to check and optimize the high pressure roller mill frame in the design phase,the statics and modal analysis of the roller mill frame is carried out,and the stiffness characteristics of the roller mill frame are analyzed according to the simulation calculation results to derive the roller axis offset.The results show that the stiffness of the roller mill frame is sufficient,and the offset of the roller axis is minimal,which meets the design requirements.The finite element analysis method can provide a more accurate calculation of the stiffness characteristics of the roller mill in the design phase and provide an effective basis for the design of the roller mill frame and the selection of the self-aligning bearings.
