摘要
基于赫兹接触理论分析了在旋转飞行器发射中2种典型高过载冲击工况下旋转隔离装置轴承内部载荷分布情况,并建立有限元模型,分析了轴承静、动态承载特性,得到了轴承零件的应力变化曲线,结果表明轴承最大接触应力在球上与内沟道接触区域。
Based on Hertzian contact theory,the internal load distribution of bearings for rotary isolation device under two typical high overload impact conditions during launch of rotary aircraft is analyzed.The finite element model is established,the static and dynamic load characteristics of bearings are analyzed,and the stress variation curve of bearing parts is obtained.The results show that the maximum contact stress of bearings is in contact area between ball and inner raceway.
