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...
Modeling and Simulation of Friction in Deep Drawing
Baspinar, Murat; Akkök, Metin (2016-04-01)
Shallow deep drawing process of a square cup is investigated in this paper. A combined friction model is introduced which integrates the Khonsari's friction model based on asperity contact and Wilson's friction model based...
Experimental analysis and wear modeling for mechanical components of a typical rail launcher
Akkök, Metin; Acar, Bulent; Acmaz, Emre (2013-08-30)
One of the most important design considerations for rocket launchers is its maintainability and one of the most important parameter which affects the maintainability is wear in launchers. Therefore, for predicting the life...
Reliability Improvement of a Solid Rocket Motor in Early Design Phases
Bozkaya, Kenan; Akkök, Metin; Esin, Alp (2009-07-01)
Designing a reliable system is difficult and costly, due to the design process to be followed and test requirements. It is important to consider reliability in very early design phases, and it is essential to select a base...
Modelling of variable friction in cold forging
Cora, Oe N.; Akkök, Metin; Darendeliler, Haluk (2008-11-01)
In metal forming operations, the friction between die and workpiece is a complex phenomenon and has a strong influence on the metal forming parameters and the product quality This study aims to investigate the effect of fr...
Determination of surface temperature rise with thermo-elastic analysis of spur gears
Taburdagitan, Murat; Akkök, Metin (2006-09-20)
The tooth surface temperature rise during meshing spur gear pair due to frictional heat is investigated. A coupled thermo-elastic analysis is carried out by considering the elastic deformation of teeth and corresponding lo...
