초록
Wheel slides may occur during train operations due to low adhesion at the wheel-rail contact patch abnormally, and the wheel slides, in turn, result in wheel flats, which affect running safety and ride comfort significantly. Thus, slide protection control has a crucial role for safe braking and prevention from wheel flats that could cause a disastrous train accident. This paper presents simulation studies on a multi-axle wheel slide protection logic with a brake system of a rolling stock including a pneumatic model for brake power supply and dump valve operation.
