Synthesis of Some Mechanisms Using Natural Coordinates

The aim of this article is to demonstrate the kinematical synthesis of some mechanisms applied in agricultural machineries. The applied method based on the use of natural coordinates for this reason the method is simple and efficient. The mechanical system is described by a set of geometric constraints. The design requirements are handled by a set of functional constraints. By the aid of objective function it can be obtained the values of design parameters of the mechanism. Finally two characteristically examples are presented that illustrate the application of the method.
