针对产品设计过程中色彩意象评价的不确定性,建立了邓氏关联度的数学模型,将用户对产品色彩意象的主观模糊表达转化为具体的色彩意象评价值,从而获得更符合用户真实意象的产品色彩设计方案。以单斗液压挖掘机色彩设计为对象进行验证,并与孟·斯宾瑟美度评价计算方法进行比较研究,实验结果显示,邓氏关联法对于产品色彩设计的意象评价更为有效。 In view of the uncertainty of color image evaluation in the process of product design, a mathematical model of Deng’s correlation degree is established, which converts the user’s subjective fuzzy expression of product color image into specific color image evaluation value, so as to obtain a more accurate image conforming to the user’s real image Product color design. The single-bucket hydraulic excavator color design was used as the object to verify the comparison. The experimental results show that Deng’s correlation method is more effective for image evaluation of product color design.
