Conference Object Citation - Scopus: 3Four-bar function generation using excel solver(Springer, 2023) Söylemez, Eres; Kiper, GökhanThe Chapter presents a simple and efficient way of approximating a function with a four-bar mechanism using four or five design parameters including one or both of the initial crank angles. The method only involves solution of linear set of equations and evaluating determinants, whereas nonlinear equations are numerically solved using a simple program such as Excel. So, the method is easy to explain and can be taught in an undergraduate course along with the wellknown linear three precision point synthesis problem. Precision point synthesis, order synthesis, mixed order synthesis, least squares approximation and extreme point synthesis can all be treated using the same method. The proposed method is illustrated with numerical examples for all mentioned synthesis problems and shown to be quite efficient with very low amount of structural error values.Conference Object Kinematic Synthesis of Planar 4-Bar Path Generators for Finite Line Positions(Springer Verlag, 2019) Kiper, Gökhan; Söylemez, EresAlthough the kinematic synthesis of planar function, point-path and motion gen-erators are vastly studied in the literature, surprisingly synthesis of line-path gen-erators is not formulized in detail. This study presents the formulization of the planar 4-bar line-path generator synthesis problem for up to 5 homologous posi-tions. Numerical examples for 3 and 4 line positions are presented for the illustra-tion of the formulations.Conference Object Citation - Scopus: 2A Comparative Study on Application of Decomposition Method in Function Generation Synthesis of Over-Constrained Mechanisms(Springer, 2014) Maaroof, Omar Waleed Najm; Dede, Mehmet İsmet CanDouble-spherical six-bar linkage is one of the Bennett over-constrained 6R linkages. Kinematic synthesis of such linkages can be tedious and impossible to solve for analytically. In order to cope with higher number of unknowns in these types of linkages, decomposition method is a valuable tool. This paper focuses on the function generation synthesis of double-spherical six-bar linkage. Two procedures for applying decomposition method are explained. Two numerical studies are conducted for both procedures to evaluate the performance of each procedure.Article Citation - WoS: 6Citation - Scopus: 8Kinematic Synthesis of Over-Constrained Double-Spherical Six-Bar Mechanism(Elsevier Ltd., 2014) Maaroof, Omar W.; Dede, Mehmet İsmet CanThe main problem in the synthesis of any mechanism is the fact that the objective function of the mechanism, which will be synthesized, should be found and simplified by using appropriate algebraic method. Finding objective function and calculation process can become complicated especially when the number of design parameters is increased for the over-constrained mechanisms. A new technique for solving the kinematic synthesis of over-constrained double-spherical six-bar mechanism is developed and applied in this work. Interpolation approximation is used during synthesis procedure. A numerical example for the kinematic synthesis procedure is given to validate the theory in application.
