依据航空发动机转子轴承的实际工况，建立轴承在稳定运转状态时的受载特性分析模型，通过将三维有限元法与线性规划法相结合，成功地求解了轴承的内圈、滚子及外圈的多物体弹性接触问题。对影响轴承受载特性的因素进行了研究，并探索了改善发动机轴承工作性能的措施，得出了有参考价值的结论 According to the actual working condition of aeroengine rotor bearing, this paper builds a model to analyze the loading characteristics of bearing under steady state. Through the combination of three-dimensional finite element method and linear programming, the bearing inner ring, roller and outer ring Multi-object elastic contact problem. The factors influencing bearing load characteristics are studied, and the measures to improve the working performance of engine bearings are explored, and the conclusions drawn with reference value
