Arc profiled wheels are now employed even in the high-speed trains to prevent unfavorable wear of wheel profile. However, the arc profiled wheel tends to increase the running vibration. Therefore, such a wheel profile is desired that the running vibration can be suppressed while the unfavorable wear is reduced. In this study, the genetic algorithm (GA) is applied to the design of profiled wheel tread which is formed from the initial cylindrical shape. Using the wheels with the obtained tread profile by GA, running simulation of a rail vehicle is carried out on a straight track and also on a curved track of 600m radius. In the comparison of the riding quality such as ride comfort and wheel lateral force with those using the existent arc profiled wheel, it is shown that the proposed method for design of wheel profile using GA has a potential to obtain a desired wheel profile.
