碩士 === 國防大學中正理工學院 === 兵器系統工程研究所 === 96 === This research used statistical concept combining the Heuristic Algorithms to the optimization design of asymmetric tolerances based on the cost analysis. The Heuristic Algorithms are used to analyze the tolerance synthesis problem for the mechanical assembly components. The purpose of this research is the introduction of automatic tolerance design for mechanical components to reduce time and cost and avoid design errors when the tolerances designed manually. The Monte Carlo analysis was used for proving the probability of the assembly tolerances of components. The airplane turbine engine components were chosen as the example for analyzing tolerance synthesis. The results showed that the Heuristic Algorithms can get the optimal solution for asymmetric tolerance design within short time based on the minimum manufacturing cost. Also , this results can be provided to design engineers as a valuable reference.
