Abstract
It is necessary that wheel tread profiles have the balance between running stability and curving performance. We have studied how to increase curving performance without decreasing running stability by changing arc wheel profile by numerical simulation. In this paper, we would like to examine the effect and its mechanism of the changed arc wheel profile by experiments. As a result, the arc wheel profile with the longer distance between the tire flange and the rail reduces side thrust without decreasing running stability. This result agrees with the analysis by numerical simulation.
