【摘要】 目的明确增材制造的手板模型常用的塑料材料,给工业设计师和生产制造工程师带来的感觉差异性,为材料选取提供合理意见。方法运用感性工学理论,构建塑料材料物理特性和感性意象词汇群的对应关系。选择适合增材制造的自由曲面形态,采用语义差异法和李克特五级量表,对6种代表性材料样本进行感觉意象认知分析,通过SPSS统计感性意象词汇测量数据,运用独立T检验方法判断了两类人群感觉是否具有显著性差异,并分析材料物理特性对感受差异性的影响。结论将抽象的感性意象词汇与材料的关键物理特性建立起感知联系,为专业人员手板模型制作过程的材料选择提供了参考。更多还原

【Abstract】 This paper is to make clear the perceptual differences between industrial designers and manufacturing engineers due to using common plastic materials for hand model of additive manufacturing, and provide reasonable suggestions for material selection. Based on kansei engineering, the corresponding relationship between the physical properties of plastic materials and the perceptual image vocabulary group was constructed. Selecting free-form surface shape suitable for additive manufacturing, and using semantic difference method and 5-point Likert scale, this paper analyzes the perceptual image of six representative material samples. SPSS was used to conduct statistics on the data of the perceptual image vocabulary measurement. The Independent-samples T-test was used to judge whether there are significant differences between two groups, and the effect of material physical properties on the perceptual difference was analyzed. The perceptual connection between abstract perceptual image words and key physical properties of materials is established, to provide reference for the material selection in the process of making hand models for professionals.更多还原
