摘　　要：为提升轿车轮毂造型设计效率,探索一种以感性意象为导向的参数化设计方法。选取目前主要的轿车轮毂造型,构建轮毂造型样本库,归纳用户对轮毂造型评价的感性意象关键词,分析造型意象与造型特征的关系;以造型特征为变量,基于Grasshopper插件构建轮毂数字模型,通过参数调节实现与造型意象的匹配关系;经过样本分析、用户评价和编程设计,确定了3对轮毂感性意象关键词,分析了5个造型特征与感性意象的关系。在Grasshopper插件中,基于6个造型特征变量,进行了轮毂的参数化设计。通过对参数化生成轮毂样本的用户评价,验证了轮毂造型意象与造型特征的关系,证明了以感性意象为导向的参数化设计方法的有效性,扩展了参数化设计的应用领域。In order to improve the efficiency of car wheel hub modeling design, a parametric design method guided by kansei image was explored.A main car wheel hub was selected to build hub modeling sample database. The kansei image keywords of user evaluation on wheel hub modeling were summarized. The relationships between kansei image and modeling features were analyzed. The wheel hub digital model was built based on Grasshopper plug-in with the variables of modeling features. The matching relationship was realized with kansei image through parameter adjustments. Three pairs of wheel hub perceptual image keywords were determined through sample analysis, user evaluation and programming. The relationships between five modeling features and kansei image were analyzed. The parametric design of wheel hub was performed in Grasshopper plug-in with six feature variables. The relationships between hub kansei image and modeling features were verified through user evaluations of the parametric wheel hub model. The effectiveness of kansei image oriented parametric design method was proved and the application field of parametric design was expanded.
