Synthesis of Planar Mechanisms, Part II: Specified Stroke, Time Ratio and Transmission Angle

Analytical synthesis of mechanisms is a useful tool towards machinery design and production. The analytical approach is useful for computer-aided design applications. Stroke , time ratio and transmission angle are important parameters in mechanism synthesis. Usually, those parameters are related nonlinearly to the planar mechanism dimensions. The paper presents an approach for the synthesis of three types of planar mechanisms fulfilling the requirements for stroke, time ratio and transmission angle. A case study is presented on each mechanism type. The synthesis is performed by deriving a set of nonlinear equations for the desired kinematical parameters of the mechanism. The MATLAB command 'fsolve' is used to solve the set of nonlinear equations and provide the optimal dimensions of the planar mechanism
