摘　　要：将 6σ概念与遗传算法和蒙特卡罗模拟技术相结合 ,构造了基于产品质量工程的 6σ概率优化设计方法 ,实现了对设计目标的优化 ,提高了产品的可靠性与稳健性。以悬臂焊接结构和弹簧的优化设计为应用实例 。Through the applications of 6σ concept and genetic algorithm and Monte Carlo simulation technique into the design optimization, the paper established a 6σ based probabilistic design optimization method. The method not only searches the optimum results for the design object, but also improves the robustness and reliability of the product. The applications of the method into the design of a welded cantilever structure and a spring are demonstrated and the robustness and reliability of the optimum design results are assessed.
