以汽车造型为研究对象,提出基于数量化理论Ⅰ类的意象造型设计方法。采用SD法获取用户对产品样本的感性意象评价;通过分析产品造型,从形态、相互位置和比例3个方面提取了对感性意象有关键影响的造型设计要素;应用数量化理论Ⅰ类建立了感性词汇与造型设计要素间的关联,并构建数学模型,以辅助产品意象造型设计。最后通过设计案例分析,表明该方法是切实可行的。 Taking automobile modeling as the research object, this paper proposes an image modeling design method based on Quantitative Theory Ⅰ. Using the SD method to obtain users’ perception image evaluation of the product samples; by analyzing the product modeling, this paper extracts the design elements that have the key influence on the sentiment image from the aspects of morphology, mutual position and ratio; Vocabulary and design elements of the relationship between modeling and building mathematical models to assist the product image design. Finally, through the design case analysis, this method is feasible.
