摘　　要： 建立了销盘实体接触的计算模型,并推导出接触应力的计算公式;利用有限元分析软件ANSYS,采用面-面接触分析,对销盘接触弹性半空间的3个应力值进行了仿真计算,并与推导的理论公式的计算结果进行比较。结果表明,在x向,ANSYS仿真值与销盘实体接触计算模型计算的应力值相差很小,在z向和xz向ANSYS仿真值稍偏大,表明利用ANSYS求解摩擦学实体表面接触问题是准确可靠的。 Calculation model of pin-on-disc substantial contact was established and calculation formula of contact stress was deduced. Three stress values of pin-on-disc contact elastic half space were simulated and calculated through making use of surface-surface contact analysis in finite element analysis software ANSYS, and the stress values were compared with the calculated results of the deduced theoretical formula. Analysis results show that simulation values of ANSYS and stress values calculated by using the calculating model of pin-on-disc substantial contact are almost equal in the x direction ,and simulation values of ANSYS is a bit bigger than the calculation values in z and xz direction. So it shows that it is exact and reliable by making use of ANSYS to look for solutions of substantial surface contact problems of tribology.
