A Study on the Safety Evaluation of Special Railway Vehicles

초록

In this paper, we investigate the process of confirming the safety of a newly manufactured US flat car by direct method on the service line. In order to evaluate the safety of driving, it is necessary to analyze the measurement of the wheel load and lateral force, the derailment coefficient and the reduction of the wheel load. In principle, it should be measured when the vehicle is running on a real track at the time of commissioning the main line because it changes variously according to the operating state of the vehicle, the track conditions, and the load conditions loaded on the vehicle. Measurement of wheel load is performed by attaching strain gauge to the wheel and installing the measuring wheel-set for measurement. In the case of this test, left and right wheels were found after loading the load. As a result, the running safety was poor when the load was loaded.
