摘要通过三维建模和有限元分析，仿真模拟了轴承的受力情况，得出了最容易产生疲劳的位置，利用L-P轴承疲劳寿命理论和滚动轴承疲劳寿命修正方法，在标准工况下，结合轴承环境温度、轴承材料性能、润滑情况、冲击载荷情况等因素，计算出了轴承的疲劳寿命，为辊磨设备寿命预测和故障预警提供了理论依据。

Abstract: By 3D modeling and finite element analysis, the analogue simulation on force analysis of bearing in detail is carried out. The position of fatigue is pointed out and the cause is analyzed. Finally, using the L-P bearing fatigue life theory and rolling bearing fatigue life correction method, under the standard working conditions, considering the bearing ambient temperature, bearing material performance, lubrication, impact load and so on, the fatigue life of bearing is calculated, which provides theoretical guidance for life prediction and fault warning of large vertical grinding equipment in industry.

Key words: vertical roller mill bearing finite element fatigue life
