In this thesis, two types of geared linkages are studied in detail. One of the mechanisms is the geared five link mechanism for which the input and output shafts are collinear. The other is a two degree-of-freedom nine-link mechanism which is called the "geared adjustable stroke mechanism". The geared adjustable stroke mechanism uses the geared five link mechanism in its structure. The geared adjustable stroke mechanism has been used in practice, but neither of these mechanisms have been studied in the literature. Analysis procedures are developed and expressions for the transmission angles of the mechanisms are derived. A synthesis procedure is proposed and charts are prepared for the design of such mechanisms.

On the synthesis of a geared four-bar mechanism
PARLAKTAŞ, VOLKAN; Söylemez, Eres; TANIK, ENGİN (Elsevier BV, 2010-08-01)
This paper presents an analysis and synthesis method for a certain type of geared four-bar mechanism (GFBM) for which the input and output shafts are collinear. A novel analysis method is devised, expressions for the transmission angle are derived and charts are prepared for the design of such mechanisms. It is observed that the GFBM considered is inherently a quick-return mechanism. Large time ratios can be obtained with acceptable force transmission characteristics. During the working stroke, approximatel...
Structural optimization strategies via different optimization and solver codes and aerospace applications
Ekren, Mustafa; Kayran, Altan; Department of Aerospace Engineering (2008)
In this thesis, structural optimization study is performed by using three different methods. In the first method, optimization is performed using MSC.NASTRAN Optimization Module, a commercial structural analysis program. In the second method, optimization is performed using the optimization code prepared in MATLAB and MSC.NASTRAN as the solver. As the third method, optimization is performed by using the optimization code prepared in MATLAB and analytical equations as the solver. All three methods provide ce...
On efficient use of simulated annealing in complex structural optimization problems
Hasançebi, Oğuzhan (Springer Science and Business Media LLC, 2002-01-01)
The paper is concerned with the efficient use of simulated annealing (SA) in structural optimization problems of high complexity. A reformulation of the working mechanism of the Boltzmann parameter is introduced to accelerate and enhance the general productivity of SA in terms of convergence reliability. Two general and complementary parameters, referred as "weighted Boltzmann parameter" and "critical Boltzmann parameter," are proposed, Several alternative methodologies are suggested for these two parameter...
A method of strain and stress analysis for failure prediction in laminated composites
Ardiç, E.S.; Bolcan, C.; Kayran, Altan (SAGE Publications, 1995-01-01)
In this study, a method of strain and stress analysis is developed to predict the failure initiation in laminated composites containing two or more different kinds of laminae. In principle, the method developed in this study is similar to non-local elasticity, but the long-range interactions are considered on the strains instead of material moduli, and the method is developed and applied as a realistic and practical one. Firstly, the strain fields in each layer are determined separately and then these strai...
Structural Optimization Using ANSYS
Panayırcı, H. Murat; Oral, Süha; Department of Mechanical Engineering (2006)
This study describes the process of performing structural optimization using ANSYS. In the first part, the general concepts in optimization and optimization algorithms for different type of optimization problems are covered. Also finite element method is introduced briefly in this part. In the second part, important definitions in structural optimization are mentioned. Then the optimization methods available in ANSYS are explained with their theories. Necessary steps to perform optimization with ANSYS are d...
