摘要
利用有限元ANSYS软件仿真与弹性力学理论对比分析某高速列车轴箱轴承与空心轴过盈配合产生的边缘效应,研究了车轴空心系数对边缘效应应力集中程度的影响规律,同时结合微动磨损理论分析增大车轴孔径在配合边缘区产生裂纹的工程现象,研究表明,空心车轴的空心系数不宜超过0.5,研究结果为空心车轴的设计、运用提供理论参考。
This paper analyzed edge effect which caused by the interference fit between axle box bearing and hollow shaft on a high-- speed train, by comparing the finite element software ANSYS simulation and the elasticity theory. The impact of hollow shaft coeffi cient to stress concentration degree on the edge is studied, and is engineering phenomenon of crack initiation in the edge area caused by increasing the hollow shaft inside ratio is analyzed by combining the fretting wear theory. The results show that the hollow＂ coefficient of hollow shaft should not be more than 0.5. It provid theory reference for the design and use of hollow shaft.
