الملخص EN

A hybrid optimization approach for the design of linkages is presented.

The method is applied to the dimensional synthesis of mechanism and combines the merits of both stochastic and deterministic optimization.

The stochastic optimization approach is based on a real-valued evolutionary algorithm (EA) and is used for extensive exploration of the design variable space when searching for the best linkage.

The deterministic approach uses a local optimization technique to improve the efficiency by reducing the high CPU time that EA techniques require in this kind of applications.

To that end, the deterministic approach is implemented in the evolutionary algorithm in two stages.

The first stage is the fitness evaluation where the deterministic approach is used to obtain an effective new error estimator.

In the second stage the deterministic approach refines the solution provided by the evolutionary part of the algorithm.

The new error estimator enables the evaluation of the different individuals in each generation, avoiding the removal of well-adapted linkages that other methods would not detect.

The efficiency, robustness, and accuracy of the proposed method are tested for the design of a mechanism in two examples.
