Demiryolu titreşimlerinin konfora etkisinin örnek hatlarda incelenmesi
Çalışmada, İstanbul’da iki farklı raylı sistemin titreşim açısından yolculuk konforları incelenerek, düşük konforlu kesimlerde nedenleri araştırılmaktadır. Bu amaçla önce Aksaray-Havalimanı hafif metro hattı ve sonra Zeytinburnu-Kabataş tramvay hattı tanıtılarak, bu hatların üstyapıları hakkında bilgi verilmektedir. Yolculuk konforunu belirlemek için yapılan titreşim ölçümünde; 3 eksenli ivme ölçer, sürücü koltuğunun altına yerleştirilmiş ve ISO 2631-4 Standardına göre ölçüm sonuçları incelenmiştir. Ölçümler sonucunda 1/3 oktav bant ivme değerlerine, frekans ağırlık filtrelerinde tanımlı kazançlar uygulanarak, ilgili eksen doğrultusunda ağırlıklandırılmış olan toplam değerler puanlama yöntemi ile değerlendirilmiştir.
Influences of railway vibrations on passenger comfort invesigation on example tracks
In this study, field vibrations were surveyed to investigate travel comfort of two different rail systems in Istanbul and the reasons of low comfort zones. With this purpose, first Aksaray-Airport metro line and then Zeytinburnu-Kabataş tram line were investigated with their superstructure information. For gathering information to determine travel comfort, a 3-axis accelerometer was placed under the seat of the driver. Results were evaluated according to the ISO 2631-4 standard. At the end of measurements, total weighted values toward the relevant axes were obtained with 1/3 octave band acceleration values by applying gains defined in frequency weight filters.
