基于遗传算法的骨骼结构模型概念创新设计

摘要

A new kind of computer aided conceptual design method was studied, control parameter of the skeleton structure theory was analyzed, the radian as control parameter was increased and the entities were analyzed. The skeleton structure parameters were optimized by Genetic Algorithm (GA), and the quality of the results of GA was optimized by controlling parents' codes. The experiment used Visual C ++ as the platform, and ACIS-HOOPS class as foundation. A conceptual design of chandelier shape was given, after abstracting skeleton structure, modeling, genetic variation and producing results of conceptual design steps, a large number of overall coordination and elegant chandelier forms were available for user to choose.%讨论了一种计算机辅助概念设计的新思路,分析骨骼结构理论参数控制,增加了弧度作为控制参数并对实体进行分析.采用遗传算法对骨骼结构的参数进行优化.通过对遗传计算中父代编码的筛选,提高了遗传算法结果的质量.实验基于Visual C++平台,利用ACIS-HOOPS类库为基础,以吊灯造型的概念设计为例,按照提取骨骼结构、建模、遗传变异、产生概念设计结果等步骤,能产生大量整体协调、造型优美的吊灯造型供用户选择.
