The dynamic behavior of a railway vehicle, such as the hunting motion of a bogie, is often tested on the roller rig of a vehicle test plant. The contact geometry between the wheel and roller rig is, however, different from that between the wheel and rail which is not curved longitudinally. Because the dynamic behavior of the railway vehicle is influenced by the difference in contact geometry, we developed a program which enables calculation of the 3-dimensional contact geometry between the wheel and roller rig. In this paper, the contact geometry between the wheel and roller rig was analyzed using 3-dimensional contact program, and the result was compared with that for the wheel and rail. It is made clear that the contact geometry of the roller rig is different from that of the rail.
