A Note on Brake System of Train Set with Wheel Slide Protection System

摘要

In railways, brake control is the important factor on safety, punctuality and etc. However, the slip is likely to occur during brake control since the wheels and rails are made of metal. The slip makes the brake distance longer and the wheels damaged. The condition of the slip is mainly due to various factors such as the load, the state of the contact surface between the wheels and the rails, so the slip becomes a high uncertainty matter. Actual train uses the blending control of regenerative brake and pneumatic brake for wheel-slide-protection (WSP), but it can be more efficient to divide braking force because each of them performs independent. In this paper, we will construct a system that distributes braking force throughout the entire train set including not only pneumatic brake but also regenerative brake. And we will evaluate of the train set brake control with electro-pneumatic blending control.
