Failure analysis of trapezium shaped carbon-epoxy plate pinned-joint
(2000)
Bu çalışmanın amacı, içinde pim bulunan yamuk şekilli, karbon-epoksi kompozitinin yırtılma mukavemetini ve modunu araştırmaktır. Yırtılma yükü ve modu nümerik olarak analiz edildi. Nümerik metod iki adım içerir: İlk olarak ...
Investigation of ball vibrations in angular contact ball bearings
(2004)
In this study, a shaft-bearing model is developed in order to investigate ball vibrations in case of defected and undefected ball bearings. In this model, shaft-bearing couple is considered as a mass-spring system and balls ...
A new method for extracting 3D solid models of objects using 2D technical drawings
(2007)
In this study, a new method called "3D-Space" have been developed to obtain 3D models of prismatic machine parts using 2D technical drawings. The algorithm basicaly works in the following manner: 3 basic views (i.e. top, ...
Modeling of the vibrations caused by ball bearing defects
(2003)
In this study a shaft-ball bearing system is modeled in order to investigate the vibrations of ball bearings with running surfaces defects. Shaft and bearing was modeled as mass-spring system and balls were assumed have ...
Determination of rolling element bearing defects through vibration analysis
(2003)
Determination of rolling element bearing defects through the available vibration analysis method is studied in this paper. Rolling element bearing defect vibrations, vibration measurement and their analysis is briefly ...
Heat transfer to a power-law fluid in arbitrary cross-sectional ducts
(2002)
Numerical solutions for laminar heat transfer of a non-Newtonian fluid in the thermal entrance region for triangular, square, sinusoidal, etc. ducts are presented for constant wall temperature. The continuity equation and ...
The minimization of absolute deviation from common due date in two machine flowshop scheduling with learning effect
(Gazi Univ, Fac Engineering Architecture, 2009)
The phenomenon of the learning effect has been extensively studied in many different areas of operational research. However, there have been a few studies in the general context of production scheduling; also there have ...
Data extraction from CAD model for rotational parts to be machined at turning centres
(Scientific and Technical Research Council of Turkey, Ankara, Turkey, 1999)
Among the most important data produced and stored is product data. CAD data forms one of many contributors to product data. Although in most circumstances CAD data can be processed within the CIM environment by integrated ...
The importance of mesh modeling in the calculation of stress intensity factor
(2001)
In this paper, stress intensity factor (SIF) of an infinite plate with a center notched hole is calculated by means of finite element method (FEM) using both triangular quadratic element (TQE) and triangular quarter point ...
A new approach for postprocessor design
(2005)
Nowadays, it can be possible that the parts which have complex shapes can be manufactured easily with the improvements on the Computer Integrated Manufacturing (CIM). Cutter Location Data (CLDATA) can be created with a ...
