A Study on the Safety Evaluation of Curved Vehicle for Transformer Transportation

초록

In this paper, we investigate the process of confirming the safety of a newly manufactured curved vehicle for transformer transportation 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. Generally, the centrifugal force under the loaded condition is larger than the empty condition. However, in this test, the lateral force was not significantly different between the two conditions. These results are considered to be due to the fact that the lateral vibration in the empty condition occurred more than the loaded condition.
