궤도의 변형에 따른 열차운행에 소요되는 전력비용 평가

초록

In the track design, it is necessary to decide the track stiffness so as to minimize the operating cost given as the sum of the maintenance cost of track and the power cost dissipated by wheels. For this purpose, it is important to accurately evaluate the power cost according to the track stiffness. In this study, an analytical method to evaluate the power dissipated by wheels, which can take into account various track and operating conditions, was presented. Using the proposed method, parameter studies were conducted to analyze the effect of track stiffness and damping, and train speed on the power dissipated by wheels. In addition, the power dissipated by wheels were evaluated in case of different track and operating conditions such as light railway, urban railway, existing railway, and high speed railway.
