Experimental Determination of Resistance Characteristics of Support Details Used in Prestressed Concrete Bridge Girders
Baran, Eray; French, Catherine; Schultz, Arturo (American Society of Civil Engineers (ASCE), 2009-09-01)
Static load tests were performed on support details used at the ends of prestressed concrete pedestrian bridge girders to determine the resistance characteristics of girder supports in the direction perpendicular to the longitudinal axis of the girders. The specimens tested represent support details that have also been widely used in prestressed concrete highway bridges in Minnesota and in other states. Two specimens, one representing the free-end detail and one representing the restrained-end detail were s...
Experimental determination of transfer functions for a car body-in-white
Şentürk, Sabri; Ünlüsoy, Yavuz Samim; Department of Mechanical Engineering (2004)
Vibration generated from various sources (engine, road surface, tires, exhaust, etc.) should be considered in the design of a car body. These vibrations travel through transfer systems (drivetrain, suspension, body, etc.) to the steering wheel, seats and other areas where it is detected by the passengers of the vehicle. Transmission routes must be studied and efforts made to keep transfer systems from amplifying vibration and to absorb it instead. Since the superior vibration transfer system is the car body...
Experimental investigation of the effects of tip geometry on the flow and loss characteristics in a linear turbine cascade
Alican, Ozan; Uzol, Oğuz; Department of Aerospace Engineering (2017)
In gas turbines, there are a number of factors causing efficiency decrease. When internal flow in turbomachines is considered, flow vortices are one of those factors. This study aims to investigate the main mechanisms behind the efficiency losses occurring due to Tip Leakage Vortex (TLV) in gas turbine rotor blades. Additionally, according to these mechanisms, two squealer tip geometries were applied to the turbine blades and the improvements were reported. This work is the experimental branch of an optimum...
Experimental Determination and Analytical Model of Friction Torque of a Double Row Roller Slewing Bearing
Dindar, Ahmet; Akkök, Metin; Çalışkan, Mehmet (2017-03-01)
In this paper, investigation on the friction torque of a double row roller slewing bearing which is operated in the azimuth axis of a gun turret is performed. For this purpose, a friction measurement test setup is designed and friction torque measurements are conducted. Tests are performed at low speeds and various loading conditions. Friction sources are decoupled and examined separately in order to fully understand effect of each component on friction torque of the slewing bearing. Therefore, friction cau...
Experimental determination of hydrodynamic dispersion coefficients for heavy metals using compacted clay
Camur, MZ; Yazıcıgil, Hasan (2001-07-27)
Mass transport of ions through the Ankara clay liner, which was prepared under three different compaction conditions, was studied experimentally on the basis of sorption, advection and hydrodynamic dispersion processes. Under optimum compaction conditions, effective porosity and hydraulic conductivity of the material were 0.32 and 0. 13-0.26 x 10(-8) cm s(-1), respectively. Effective diffusion coefficients of Cd, Cl, Cr, Cu, Fe, K, Mg, Mn, Ni, Pb and Zn ions were, respectively, 2.54, 9.51, 2.22, 2.85, 2.22,...
