Abstract

Wheel slip rate control using synchronized speed pulse computing N.Kumagai*, S.Uchida^, I.Hasegawa^, K.Watanabe^ 1 Planning Division, Railway Technical Research Institute, Japan 2 Rolling Stock Tech. Dept, Railway Technical Research Institute, Japan 3 East Japan Passenger Railway Co. Ltd., Japan Abstract Anti-skid brake control systems for wheel slide protection have been installed on recent rolling stocks. In such systems, it is essential to avoid increasing of braking distance and causing wheel flats under wet condition. In order to improve air braking pressure control and to keep wheel slip rates small in micro- slip wheel rotation, an anti-skidding brake control system named the slip rate control and a new pressure intensifier cylinder which had wheel slide control valves were developed for the Shinkansen brake. The measures processing speed pulses achieved shorter calculation time of each wheel speed/deceleration and rapid wheel slip detection We obtained a good
