Resumen/Descripción – provisto por el repositorio digital
The objective of this research work is the study and development of techniques for the design and synthesis of planar-linkage mechanisms starting from the initial specifications or design requirements. The synthesis of mechanisms consists in finding the suitable mechanism for a given movement. In order to solve this difficult problem, it is proposed to use a representation of the mechanism based on the Finite Elements Method and Graph Theory, managing to preserve and unify both representations to integrate the synthesis into its subsequent stages of detailed design. The original theoretical aspects presented in this thesis are: (i) The development of a new identifier of isomorphism of mechanisms and its use in the enumeration of kinematic chains and different atlases of mechanisms. (ii) The exhaustive enumeration of topologies using sub-graphs search to satisfy structural requirements. (iii) The automatic decomposition of the closed-loop topologies into single open chains to solve their dimensional synthesis using analytical equations. (iv) For the dimensional synthesis, all combinations of single open chains (some of them with multiple solutions) are automatically computed using Genetic Algorithms. (v) The modifications for designing flexible mechanisms using Rigid-Body Replacement methods are developed. As the final result of the application of this technique, it is obtained a list of alternatives that constitute good initial conditions for subsequent gradient-based optimization. Throughout the thesis, various test and validation examples are provided, showing the capacity of the inventive tool developed.Palabras clave – provistas por el repositorio digital
