【摘要】：美是客观存在的,美感则是人的主观心理感受。一个好的产品设计首先是美的设计。伴随着科学技术的发展和竞争的加剧,产品的创新设计出现了越来越多的方式,设计出符合使用功能的产品已远远无法满足消费者的需求,满足消费者的美感需求和产品形式的愉悦感才是设计师和企业面临的挑战,而产品的形态在满足消费者的审美感受上占有非常重要的地位。基于此,本研究从分析审美认知和视知觉原理出发,总结影响产品形态美度评价的函数知识库,构建产品形态美度量化指标与美感之间的映射关系,为产品形态设计和开发提供有效辅助手段。其主要研究包含以下三方面内容。第一,分析审美认知和视知觉原理,挖掘完形心理学、形式美法则、伯克霍夫美学理论和黄金分割等潜在美学评判知识,总结了12个产品形态美度评判形式,对美学评判知识建立数理方程式,以此构筑产品形态美度的评价函数知识库;并以紫砂壶为例对知识库中的美度指标进行计算,实现对产品形态进行客观评价的目的。第二,利用感性工学获得消费者的美感意象,并运用聚类分析法获得目标产品形态美感的具体形式,并以紫砂壶为例得到代表性美度指标,分别为对称度、比例度、秩序度和偏离常态度,为建立外显形态和内隐美感的关系提供了依据;再运用结构方程模型,表征了产品形态与人的视知觉认知的逻辑关系,为建立产品形态美度评价系统奠定了基础。第三,采用人工神经网络构建了产品形态美度评价系统,以代表性美度指标为输入和以美度评价为输出;并用紫砂壶为实例,对BP神经网络进行训练和验证分析;再选择设计师设计的两款形态差异较大的紫砂壶为应用实例,结果表明该方法对于产品形态的美度评价具有较好的适用性,在计算机辅助产品形态设计中将具有良好的应用前景。
[Abstract]:Beauty exists objectively, and aesthetic feeling is subjective psychological feeling. A good product design is first of all beautiful design. With the development of science and technology and the intensification of competition, there are more and more ways of innovative design of products, which can not meet the needs of consumers. It is the challenge for designers and enterprises to meet the aesthetic needs of consumers and the pleasure of product forms, and the form of products plays a very important role in satisfying the aesthetic feelings of consumers. Based on this, this study analyzes the principles of aesthetic cognition and visual perception, summarizes the functional knowledge base that affects the evaluation of product form beauty, and constructs the mapping relationship between the quantitative index of product form beauty and aesthetic feeling. To provide effective auxiliary means for product form design and development. Its main research includes the following three aspects. First, it analyzes the principle of aesthetic cognition and visual perception, excavates the latent aesthetic judgment knowledge, such as gestalt psychology, formal beauty rule, Birkhoff's aesthetic theory and golden section, and summarizes 12 forms of product shape beauty evaluation. The mathematical equation of aesthetic judgment knowledge is established to construct the knowledge base of evaluation function of product form beauty, and the beauty index in knowledge base is calculated by taking purple sand pot as an example to realize the objective evaluation of product form. Second, using perceptual engineering to obtain the aesthetic image of consumers, and using cluster analysis to obtain the specific form of aesthetic perception of the target product form, and taking the purple sand pot as an example to get the representative beauty index, which are symmetry degree and proportion degree, respectively. The degree of order and deviation from normal attitude provide the basis for establishing the relationship between explicit form and implicit aesthetic feeling, and then use the structural equation model to express the logical relationship between product form and human visual perception. It lays a foundation for establishing the evaluation system of product form beauty. Thirdly, the artificial neural network is used to construct the evaluation system of product form beauty, which takes representative beauty index as input and beauty evaluation as output, and uses purple sand pot as an example to train and verify BP neural network. Then two different purple sand pots designed by designers are selected as application examples. The results show that this method is suitable for evaluating the beauty of product form. It will have a good application prospect in computer aided product shape design.
