광섬유 센서를 이용한 열차 윤중 측정 장치 개념설계

초록

Railway bogie is composed of the bogie frame to support the load of the car body firmly and deliver the force of traction or the braking power to a train and various electrical & mechanical components such as transmission, brake system, wheel set, axle, axle box, and etc. During the commercial operation, when some components of the bogie are damaged, the diagonal balance may break down which can induce the derailment of the train and unevenly wear the rail. In this paper, we made a conceptual design of wheel load detection system for every wheel which can be used to check the diagonal balance of the bogie and various parameters to influence the derailment of train. Distributed optical fiber sensors are embedded in the rail and data logger is installed on the wayside of the rail which has a spatial resolution of an order of centimeter to satisfy the pointed contact between the wheel and rail.
