도시철도 전차의 정위치 정차 제어에 관한 연구

While trains perform a complete precision stopping control at stop point, it is essential to keep better commuters comfort in prompt. Because a train's brake force tends to increase a brake effort in a low speed and a low brake effort, a brake force in motor cars must be increased to keep better passenger comfort. to control the special braking qualities and to prevent the impact of the automatic coupler rather than trailer's. Rail cars must have a special braking process for the train stopping control. In the train slop mode, the train stopping control is designed to start at 20㎞/h. It starts by Dynamic brake blending, and then finally stops by only the friction. If these process are not exactly activated, the train may fail a complete precision stop. In this report, it studied the electric and friction brake processing during the precious stopping control. To achieve exact test results, the speed reference has to be reduced the calculated difference. In the precision stopping control. the ways of the keeping brake terce in motor car was analyzed and some solutions or controling air pressure was brought up by means or direct test in main line. This study was based on line 5 in Seoul Metropolitan subway
