功能梯度材料圆柱滚子轴承材料设计

Study of Material Design for Cylindrical Roller Bearings Made of Functionally Gradient Materials

为了解决轴承"边缘效应"问题,提高轴承的承载能力,采用有限元法对功能梯度材料圆柱滚子轴承滚动体的轴向材料性能、对轴承最大等效应力的影响进行了研究.研究结果表明:当滚动体轴向材料性能设计合理时,在一定程度上可以降低轴承滚动体的最大等效应力,降低或避免轴承滚动体"边缘效应"问题.

In order to solve the problem of ＂edge effect＂ and increase the load capability for cylindrical roller bearings made of functionally gradient materials, the effect of axial material properties on the maximum equivalent stress is studied with finite element analysis. The analysis results show that the reasonable design of axial material property could decrease the maximum equivalent stress, reduce/solve the problem of ＂edge effect＂.
