Abstract

The performance of the railway bogie is classified into the stability and the steering performance. Testing for the bogie stability is conducted on the roller rig, but testing for the bogie steering performance on test facility is very difficult, so the testing for the vehicle curving performance is conducted on the real curve track. Testing the railway bogie on the full scale test rig is desirable, but it caused many problems relating to test costs and test time. As a possible alternative to overcome these problems, a small scaled test rig is actively used in the field of bogie stability. Thus, in this paper, we have studied a scaled track to test the bogie steering performance. For this purpose, we designed the 1/5 scaled test track equivalent to radius 200 curve and confirmed the validity of the testing for the bogie steering performance on the sealed curve track through the testing using 1/5 scaled bogie.

철도차량의 곡선주행성능은 유지보수관점에서 매우 중요하다. 곡선주행성능과 관련된 대차의 조향성능은 실차를 이용한 실선로 주행시험이 적전하나 차량 개발단계에서는 이를 검증하기가 용이하지 않다. 따라서 차량의 조향 특성을 효율적으로 시험하기 위한 축소 곡선트랙에 대한 연구를 수행하였다. 대차의 곡선 주행을 모사하기 위한 곡률반경 $200{\sim}250m$의 급곡선과 등가인 1/5 scale 규모의 축소 곡선트랙을 설계, 제작하였다. 1/5 scale 대차를 이용한 주행시험 시험결과 곡선 주행특성이 비교적 잘 반영되고 있음을 확인하였다.
