A connecting way by bolts is used in machine tools. In these connections, especially, it has been known that the rigidity of the connection when a column is joined to a base effects on total rigidity of machine tools. In reasonable designing of these connections, it is necssary to know the contact stress distribution between the column and the base more exactly. In this paper, by replacing the flange of the column and the base by two finite cylinders respectively, discussion is made on the contact stress distribution when two different finite cylinders are compressed together. Following results are obtained. 1) The method to analyze the contact stress distribution is shown as a two body contact problem using three dimensional theory of elasticity. 2) Numerical results show the effects of elastic moduli, heights of finite cylinders and positions of a load application on the contact stress distribution.
