Abstract
Curving performance is important for railway vehicle. In a railway bogie, a wheelset in which the right and left wheels are rigidly coupled with the wheel-axle is generally used. The wheelset causes noise and wear due to insufficient wheel diameter difference in a sharp curve with a radius of about 10 meters existing in a tram. Using independently rotating wheels gives potential effectiveness, and authors proposed a self-steering bogie with independently rotating wheels which makes the most of gravity restoring force. However, a steering bogie with independently rotating wheels for a driving bogie has not been considered in our research. Even though some researches regarding active steering bogies exist, active steering bogie with traction which enables ideal curving is not realized on service operation. In this paper, we propose an active steering bogie with traction which measuring the wheel lateral displacement and the angle of attack with displacement sensors. As a result of numerical simulation with SIMPACK, proposed bogie and its control strategy are confirmed that the bogie has excellent steering performance on a sharp curve.
