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.Conference Object Function Generation of a Watt Ii Type Planar Mechanism With Prismatic Output Using Decomposition and Correction Method(Azerbaijan Technical University, 2017) Kiper, GökhanThe method of decomposition is a useful method for function generation with multi-loop mechanisms. Recently introduced correction methods applied together with the method of decomposition allows the designer to cancel out the errors in the first loop of a two-loop mechanism with the errors in the second loop. In this study, the decomposition and correction method is applied for a Watt II type planar six-link mechanism with prismatic output. Five design parameters are defined for each loop resulting in ten design parameters in total. The design parameters are determined analytically. The generation error is decreased by adjusting free parameters such as limits of some joint angles and parameters due to the decomposition of the function to be generated, while considering several constraints such as link lengths ratios and ranges of the joint variables. The success of the method is illustrated with a numerical example.
