摘　　要：为了在设计阶段能对高压辊磨机机架进行精准的计算与优化,采用有限元分析方法对辊磨机的机架强度进行了仿真分析,得出其应力分布状况。根据其应力分布状况和辊磨机激励的常幅谱进行了疲劳分析,仿真计算出机架的疲劳寿命云图。结果表明:辊磨机机架强度足够,疲劳寿命为永久,满足设计要求。采用有限元分析方法可对辊磨机机架的强度和疲劳寿命进行比较准确的计算,对辊磨机机架的设计以及结构优化提供有效的计算依据。In order to accurately calculate and optimize the frame of high-pressure roller mill in the design stage, the frame strength of HPRM is simulated and analyzed by FEA method, and its stress distribution is obtained. According to the stress distribution and the constant amplitude spectrum of roller mill excitation, the fatigue analysis is carried out, and the life cloud diagram of its frame is obtained by simulation. The results show that the strength of the roller mill frame is sufficient, and the fatigue life is permanent, which meets the design requirements. The FEA method can accurately calculate the strength and fatigue life of the HPRM frame, and provide an effective calculation basis for the design and structural optimization of the HPRM frame.
