Abstract

The Eddy current brake (ECB) is a new technology brake system that can be used as an emergency or service brake for trains on railway lines. In this system, the main force for braking is caused by the electromagnetic interaction between the magnet assembly and the rail, independent of the adhesion between the wheel and the rail. This increases the braking performance of the train. This system is recommended as the best option for high speed trains, given the improvements in capacity, safety and maintenance costs. However, it is necessary to check the compatibility of this system with the conventional railway line and make it available under certain conditions. In this article, the compatibility between the current high-speed railway lines and its components with the Eddy-Current brake system in Turkey was evaluated with the help of theoretical calculations considering their contributions to the traffic capacity and maintenance cost of this system and proposals have been made on the implementation of the solution.

Eddy Current Fren Sisteminin Türkiye’deki Yüksek Hızlı Demiryolu Hatları ile Uyumunun Analizi

Abstract

Eddy-Current freni (ECB), demiryolu hatlarında trenlerin acil durum ya da servis freni olarak kullanılabilecek yeni teknoloji fren sistemidir. Bu sistemde frenlemeye esas kuvvet, tekerlek ve ray arasındaki adezyondan bağımsız olarak mıknatıs düzeneği ve ray arasındaki elektromanyetik etkileşim ile ortaya çıkmaktadır. Böylece trenin frenleme performansı artmaktadır. Bu sistem, kapasite, emniyet ve bakım maliyetlerinde sağladığı iyileştirmeler göz önüne alındığında yüksek hızlı trenler için en iyi seçenek olarak önerilmektedir. Ancak, bu sistemin, konvansiyonel demiryolu hattı ile uyumunun kontrol edilerek belirli koşullar altında kullanıma sunulması gerekmektedir. Bu makalede, Türkiye’deki mevcut yüksek hızlı demiryolu hatları ve bileşenlerinin Eddy-Current fren sistemine olan uyumu ile bu sistemin trafik kapasitesine, bakım maliyetine olan katkıları teorik hesaplamalarla değerlendirilmiş, uygulama çözümlerine ilişkin öneriler sunulmuştur.
