Abstract

Bu çalışmada iki boji ve sekiz dingile sahip bir raylı sistem aracının dikey yöndeki dinamik karakteri incelenmiştir. Birincil ve ikincil süspansiyon sistemlerinde yer alan viskoz damperlerin ayrı ayrı arıza durumları dikkate alınmıştır. Her bir arıza durumunda araç gövdesinde meydana gelen frekans cevapları incelenerek sürüş konforu ve seyir güvenliği açısından değerlendirmeler yapılmıştır. Raylı sistem aracının 60 km/s sabit seyir hızı dikkate alınarak 10 mm derinliğinde lokal bir ray çökmesi üzerindeki dinamik tepkileri incelenmiştir. Araç gövdesinin 10 serbestlik dereceli dinamik modeli oluşturulmuştur. Elde edilen denklemler Simulink paket programında blok diyagramları oluşturularak Runge-Kutta (Ode45) tekniği ile nümerik olarak çözülmüştür. Araç gövdesinin dikey ve açısal yöndeki frekans cevapları alınarak ivme değerleri hesaplanmıştır. Benzer şekilde spektral güç yoğunluğu fonksiyonları da elde edilmiştir. Elde edilen sonuçlarda damper arızalarının sürüş konforunu bozucu etkiler ortaya çıkardığı tespit edilmiştir. Boji 1 ve 2’nin birinci damper arızaları titreşim genliklerini arttığından dolayı kritik olarak değerlendirilmiştir. Birincil süspansiyon sistemindeki damper arızalarının kritik olduğu ve ikincil süspansiyon sistemindekilerinin ise sürüş konforunu önemli ölçüde değiştirmediği sonucuna varılmıştır.
