Optimization of ride comfort for vehicles equipped with passive and active hydro-pneumatic suspensions
Sağlam, Ferhat; Ünlüsoy, Yavuz Samim; Department of Mechanical Engineering (2016)
The main objective of this study is the optimization of ride comfort performance of vehicles equipped with Hydro-Pneumatic (HP) suspension systems. In order to improve ride comfort performance together with handling behavior as a constraint, active-passive, and unconnected-interconnected HP suspension systems are included in the study. The basic HP suspension model is developed and validated by experiments. Various HP suspension systems of increasing complexity are modeled, and their dynamic characteristics...
Assessment and simulation of car access control policies in city center: the case of Tunalı Hilmi Street in Ankara
Doğan, Murat; Babalık, Ela; Tüydeş Yaman, Hediye; Department of City and Regional Planning (2014)
Since the Second World War, private car use has been increasing in the world, affecting particularly urban areas and their city centers, which suffer from severe levels of congestion, pollution and traffic safety problems. In order to solve traffic problems in city centers, there needs to be a policy for car access control, which can be achieved through Travel Demand Management and Traffic Management. This study, analyses possible effects of transforming the Tunalı Hilmi Street in Ankara into a pedestrian a...
Investigation of turbulence models used in automotive industry
Taştan, Umur; Çetinkaya, Tahsin Ali; Department of Mechanical Engineering (2011)
In this study; reliability and performance of turbulence models used in CFD softwares to determine the aerodynamics of passenger cars, are tested and compared. In the analyses, drag forces acting on the car, pressure and velocity distributions and wake flow patterns are determined by using several turbulence models with a commercial software Fluent. Calculated results compared to the experimental results given in the literature. It is observed that, turbulence models give relatively reliable results for det...

Best Option for Reducing On-Campus Private Car-Based CO2 Emissions: Reducing VKT or Congestion?
Altıntaşı, Oruç; Tüydeş Yaman, Hediye (2016-01-01)
Reducing carbon emissions, especially that of private car use, is an inevitable goal of sustainable transportation policies. This study focuses on i) determination of the current level of CO2 emissions from private cars on the Middle East Technical University (METU) campus and ii) evaluation of the impact of different emission reduction scenarios. Such scenarios were based on hypothetical conditions that can either reduce Vehicle-km-travelled (VKT) or congestion on campus, which are defined as the two major...
