中文摘要：
目的探索影响汽车造型边界和认知范畴的规则,进而辅助汽车造型设计和计算机辅助造型生成。方法提出了一种规则表达的汽车造型＂原型特征＂抽取方法,首先将汽车造型问题映射到规则模型上,然后以规则表达方式抽取对汽车造型原型有影响的几何阈值特征、几何逻辑特征、工程特征和品牌特征。结果这些特征共同组成了该车型、该品牌的汽车造型原型特征。结论此成果已经应用在基于进化思想的汽车造型优化设计方法中,对于造型与工程整合,计算机辅助造型生成以及评价具有重大作用。以小型两厢车为例,证明了该方法的合理性和可行性,此方法亦可用于其他车型和品牌＂原型特征＂的抽取。
英文摘要：
In order to explore the styling rules which affects automotive styling border and modeling cognitive areas, and thus assist automotive design and computer-aided modeling generation. It proposed a automotive styling ＂prototype feature＂ extraction method based on mathematical expression, by mapping problems of automobile styling to mathematical model, and extracted geometric threshold feature, geometric logic features, engineering characteristics and the characteristics of the brand from the model and brand dimensions. Eventually these features came together to form the prototype of this styling. This result has been applied in automotive styling based on evolutionary optimization method, has generated a major role for modeling and engineering integration, computer-aided modeling and evaluation. We prove the rationality and feasibility with an example of a small hatchback. This method can be also extended to the other models and brand.
