Positional Synthesis of RRRR Linkage Using Evolutionary Computation

In this work, an algorithm based on evolutionary computation is used to solve positional synthesis for RRRR linkage. The main result allows to synthesize a linkage that satisfy higher amount of design pairs [input,output] than obtained by algebraic methods. The design pairs are important in every mechanic synthesis because specify a desired trajectory of the mechanism; however, algebraic methods avoid to use a high number of pairs. In the proposed approach, more design pairs can be involved generating more equations so more solutions can be considered. Numerical results and simulations are shown in order to illustrate the performance of the proposed approach. Finally, some discussions and conclusions are given.
