Weight Reduction of Intercity Bus by Different Seat Construction Design in Compliance with APTA and FMVSS Standards

Bu çalışmada, şehirlerarası otobüslerde farklı koltuk yapı dizaynlarının ağırlık azaltma potansiyeli değerlendirilmiştir. Yolcu koltukları bilgisayar destekli yazılım modeli olarak tasarlanmıştır. FMVSS ve APTA standartları testlerini simüle etmek için sonlu elemanlar yöntemi kullanılmıştır. Koltuk dizaynlarını doğrulamak için, sonlu elemanlar analiz metodu ile yapılan test simülasyonları sonucunda elde edilen toplam deformasyon ve maksimum stres değerleri incelenmiştir. Çalışma sonuçları koltuklarda çelik yerine alüminyum alaşım kullanmanın %50 ağırlık azalışı sağlayacağını göstermiştir. Bu ağırlık azalışı araç ömrü süresince CO2 emisyonlarını azaltabilir ve yakıt verimliği de sağlayabilir.

Şehirlerarası Otobüslerde APTA ve FMVSS Standartları'na Uygun Farklı Koltuk Yapısı Dizaynları ile Ağırlık Azaltılması

In this study, weight reduction potential of different seat construction designs has been evaluated for intercity bus. The passenger seats were designed as CAD model. Finite element method was used to simulate the tests of FMVSS and APTA standards. Total deformation and maximum stress parameters, which were obtained by test simulations in FEA software, were analyzed to verify seat designs. This study results show that using aluminum alloy for seat design instead of St-37 steel provide 50% weight reductions for seat design. This weight reduction can reduce CO2 emissions and also provide fuel efficiency over the vehicle"s operating life.
