Abstract: Line side of the main features in the organism for the study, it proposes the establishment of user-based imagery bionic design ideas and methods of gene libraries processes designed to improve access to designer bionic prototypes. It selects the organism side contours as the research object, uses Bezier curves to quantify the description. It gets user expectation imagery adjectives through research, critical imagery vocabulary is got through cluster analysis and quantified characteri-zation, it enters the library to obtain biologicalprototype. In u-fi cat design, it verifies rationality and feasibility of the method.

Key words: bionic design, shape design, expectation imagery adjectives, gray relational clustering, computer-aided design

摘要： 以生物体侧面主特征线为研究对象，提出了建立基于用户意象的仿生设计基因库思想和方法流程，旨在提高设计师对仿生原型的获取。选取生物体侧面轮廓线作为研究对象，利用贝塞尔曲线将其量化描述；通过调研获得用户期望意象形容词，经过聚类分析得到关键意象词汇并将其量化表征，输入库中获取生物原型。以u-fi猫的设计验证了该方法的合理性和可行性。
