초록

본 연구는 안내레일을 이용한 고무차륜 AGT 궤도의 주행로 연마 효과분석으로서 주행로 연마 전, 후의 고저, 수준, 평탄성, 평면성 및 차량진동가속도의 변화 값을 비교 분석하여 안내레일을 이용한 주행로 연마의 효과를 실험적으로 입증하였다. 안내레일을 이용한 주행로 연마 전, 후의 고저, 평탄성, 수준 측정결과, 주행로 연마 전, 후 곡선구간은 약 50%, 직선구간은 약 33% 개선효과가 나타난 것으로 분석되었으며, 고저 측정결과, 곡선구간에서 71%, 직선구간에서 약 43%의 개선효과가 있는 것으로 분석되었다. 또한 평면성 측정결과, 곡선구간은 약 57%, 직선구간은 약 33% 개선효과가 나타난 것으로 분석되었다. 수준(레벨기)측량 결과를 이용한 연마 효과 분석결과, 직선구간에서보다 곡선구간에서 주행로 연마 시 효과가 탁월한 것으로 분석되었다. 주행로 연마 시 차량 진동가속도 분석결과, 차량의 속도가 높을수록 주행로 연마 효과가 더욱 커지는 것으로 분석되었다. 그러나 본 연구는 곡선구간 주행로에 따른 횡단 경사량이 미포함되어 횡단 경사량을 포함하는 곡선부 주행로 연마 및 방법에 대한 추가적인 연구가 필요할 것으로 판단된다.

This study analyzed the effect of running path grinding on a rubber-wheeled AGT track using a guide rail, and experimentally verified the effect of running path grinding using a guide rail by comparing and analyzing the changes in vertical, level, flatness, twist and vehicle vibration acceleration before and after running path grinding. The results of measuring vertical, flatness, and level before and after track grinding using guide rails showed that the curved sections showed approximately 50% improvement effects and the straight sections showed approximately 33% improvement effects before and after track grinding. The results of measuring vertical showed that the curved sections showed approximately 71% improvement effects and the straight sections showed approximately 43% improvement effects. In addition, the results of measuring flatness showed that the curved sections showed approximately 57% improvement effects and the straight sections showed approximately 33% improvement effects. The results of analyzing the grinding effect using the results of level measurement showed that the track grinding was more effective on curved sections than on straight sections. The results of the vehicle vibration acceleration analysis during the driving path grinding showed that the higher the vehicle speed, the greater the driving path grinding effect. But, this study does not include the cross-slope according to the curved section driving path. It is judged that additional research is needed on the polishing and method of curved section driving paths including the cross-slope.
