Abstract

Rail corrugation is continuously increasing due to the lack of maintenance regulations for the amount of rail irregularities. Rail corrugation is causing various problems, such as a decrease in ride comfort and an increase in the amount of track maintenance. In this paper, the effect of rail corrugation on the track force was analyzed by measuring the rail irregularities before and after rail grinding and the track measurements (dynamic wheel load, displacement, and acceleration) for the section where the rail corrugation occurred. In addition, it was experimentally proven that the rail grinding performed to reduce the corrugation of the rail was very effective in reducing the additional forces on the track.

레일 파상마모는 레일표면 요철 관리기준의 부재로 인해 지속적으로 증가하는 추세에 있다. 레일파상마모는 승차감 저하와 궤도 유지관리 물량증대 등과 같은 다양한 문제점을 야기 시키고 있다. 본 논문에서는 레일 파상마모 발생구간을 대상으로 레일 연마 전, 후에 대한 레일요철 측정 및 궤도계측(동적 윤중, 변위, 가속도)을 수행하여 레일 파상마모가 궤도부담력에 미치는 영향을 분석하였다. 또한 레일 파상마모 저감을 위해 실시한 레일연마는 레일 파상마모로 인해 발생되는 추가적인 궤도부담력 저감에 매우 효과적이었음을 실험적으로 입증하였다.
