摘　　要：轴孔过盈配合由于其结构简单、承载能力高,在工程中得到广泛的应用,但其配合接触面应力分布复杂,边缘处出现应力集中。用拉普位移函数和位移势函数叠加的方法给出了位移函数,该位移函数满足轴孔过盈配合空间轴对称问题的弹性力学微分方程和边界条件,从而求出了轴孔过盈配合空间轴对称问题应力和位移的解析解。通过对边界条件的设定,对轴孔过盈配合中接触边缘应力集中进行解析分析,给出了在设定边界条件下的解析解,分析了产生应力集中的原因,并提出了减小应力集中的方法。The interference fit join of hub, owing to simple structure and effective bearing capacity, obtains the widespread application in the engineering, but its stress distribution of coordinative contact is complex and edge presents the stress concentration. The displacement function which satisfies axial symmetrical elastic mechanics differential equation and the correspondence boundary conditions is carried out by adding Lapu displacement function and displacement function, gives out analytical solutions for displacement and stress of interference fit join of hub. Analytical solutions fringe stress concentration, then, analyses the concentration are presented by establishing causes of it and proposes the boundary conditions to some methods to reduce the stress concentration.
