摘　　要：目前多数的轻量化研究,通常基于尺寸、形状、位置等某一单方面的设计因素展开,而忽略了各因素之间的交互性。另外,设计变量在制造生产过程中不可避免的存在一定范围内的波动。针对现有车门产品,结合多种类的设计因素,并考虑设计变量的波动对产品性能的影响,采用试验设计方法构造高精度的响应面模型,结合多岛遗传算法、蒙特卡罗模拟技术,对车门结构进行6σ稳健性与轻量化改进设计。结果表明,本研究在减轻车门质量的同时显著提高了产品性能及性能的稳健性。Most of the current lightweight studies are usually based on a single design factor, such as size, shape, position, and so on, while ignoring the interactivity between the factors. In addition, design variables inevitably fluctuate in a certain range in the manufacturing process. For the existing door products, combining the variety of design factors, and the effect of the fluctuation of design variables on the performance of the product is considered. The high precision response surface model is constructed by the experimental design method, and the six sigma robust and lightweight design of the door structure is improved by combining the multi-island genetic algorithm and Monte Carlo simulation technology. As a result, the quality of the door is reduced and the robustness of the product is improved.
