Because the train running speed is getting higher, it should be considered at the development stage of the bogie to prevent the hunting. General thought is that the hunting velocity is same when the equivalent conicity is the same value, hi this study, measurement of the wheel tread shape at some mileages and the equivalent conicity calculation are done. Then simulation for the hunting velocity with the actual worn wheel tread is done. The results have the different hunting velocity, even when the equivalent conicity is the same value. The result in this study makes clear that the hunting velocity is higher when the contact area between rail and wheel in the rail direction is longer.
