Abstract: The mathematical model for reliability-optimum design of cylindrical helical spring is set up based on reliability criterion. This paper proposes a kind of synchronous cellular genetic algorithm by combing genetic algorithm with cellular automat theory. The proposed algorithm not only reserves the superiority of genetic algorithm, but also has the advantage of cellular automat, which can effectively protect the algorithm from premature convergence. The feasibility and significance of the proposed algorithm are proved by the results comparison of the examplesof cylindrical helical spring reliability optimization design.
