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 caused by rolling motion and friction caused by two different types of lip seals are investigated. In addition, friction identification analyses are performed. In the analysis, load distribution of the bearing is calculated by finite element analysis software and rolling motion is simulated with a multibody-dynamic analysis program. In the end, analyses results are compared and verified with the test results.

Comparison of chevron and suspended-zipper braced steel frames Ozcelik, Yigit; Sarıtaş, Afşin; Clayton, Patricia M. (2016-03-01) Suspended-zipper braced frame is a modified configuration of chevron braced frame in which zipper columns are added between story beams and a hat truss is attached between top two stories in order to redistribute the unbalanced vertical forces emerging following the brace buckling to avoid the use of deep beams. In this study, three- and nine-story chevron and suspended-zipper braced frames are analyzed to compare their seismic performances. The beams, columns, braces and zipper columns are modeled using no...
Experimental investigation on sharp crested rectangular weirs Şişman, H. Çiğdem; Altan Sakarya, Ayşe Burcu; Department of Civil Engineering (2009) Sharp crested rectangular weirs used for discharge measurement purposes in open channel hydraulics are investigated experimentally. A series of experiments were conducted by measuring discharge and head over the weir for different weir heights for full width weir. It is seen that after a certain weir height, head and discharge relation does not change. Hence a constant weir height is determined. For that height; discharge and head over the weir are measured for variable weir width, starting from the full wi...
Structural stability and electronic properties of different cross-sectional unstrained and rectangular cross-sectional strained GaP nanowires Mohammad, Rezek; Katırcıoğlu, Şenay (World Scientific Pub Co Pte Lt, 2019-02-10) The stability and electronic properties of the hexagonal, trigonal and rectangular cross-sectional GaP nanowires in wurtzite (WZ) phase are investigated using full potential linear augmented plane waves method. The rectangular cross-sectional nanowires are found more stable than the hexagonal and trigonal ones. The indirect bandgap structure of the nanowires is transformed into the direct bandgap one at a critical size connected to the geometry of the cross-section. The energy bandgap of the nanowires in th...
Experimental investigation of the effects of tip-injection on the aerodynamic loads and wake characteristics of a model horizontal axis wind turbine rotor Abdulrahim, Anas; Uzol, Oğuz; Department of Aerospace Engineering (2014) In this study, tip injection is implemented on a model Horizontal Axis Wind Turbine (HAWT) rotor to investigate the power and thrust coefficient variations as well as the wake characteristics. The model wind turbine has a 0.95 m diameter 3-bladed rotor with non-linearly twisted and tapered blades that has NREL S826 profile. The nacelle, hub and the blades are specifically designed to allow pressurized air to pass through and get injected from the tips while the rotor is rotating. The experiments are perform...
Comparison of Linear and Nonlinear Modal Reduction Approaches Ferhatoğlu, Erhan; Dreher, Tobias; Ciğeroğlu, Ender; Krack, Malte; Özgüven, Hasan Nevzat (null; 2019-01-31) Periodic vibration response of nonlinear mechanical systems can be efficiently computed using Harmonic Balance Method. However, computational burden may still be considerable and impede extensive parametric studies needed for, e.g., design optimization and prediction of vibration response especially when the degree of freedom is very large. In this work, the methods which had been previously developed by the authors for further model order reduction to one or a few coordinates are compared. The focus is pla...
