基于形状文法的电动汽车品牌继承性设计方法

Design Method of Electric Vehicle Brand Inheritance Based on Shape Grammar

目的电动汽车造型设计既要满足电动特征的造型创新,又要保证品牌基因的识别性继承,在双重驱动和限制下,对电动汽车的品牌继承性设计方法进行研究。方法基于形状文法理论,通过将提取出的既有品牌造型特征应用一定的变化规则进行推演,可产生大量满足品牌继承性要求的全新电动汽车造型。结果电动汽车的造型变化规则包括品牌总结、技术要求和用户期望意象,三者共同约束和指导电动汽车的造型设计。结论以宝马电动汽车设计为例验证了方法的可行性,方法可以在保证品牌识别的同时有效指导电动汽车的造型创新。

The work aims to study the brand inheritance design method of electric vehicles under double drive and limitation,with respect to the fact that the modeling design of electric vehicles should not only meet the modeling innovation of electric characteristics,but also ensure the identification inheritance of brand genes.Based on the theory of shape grammar,the extracted existing brand modeling characteristics were deduced with certain change rules,thus producing a large number of brand-new electric vehicle modelings that met the brand inheritance requirements.The rules for modeling changes in electric vehicles include brand summary,technical requirements and image expected by user.All of them jointly restrained and guided the modeling design of electric vehicles.The feasibility of the method is verified with BMW electric vehicle design as an example.The method can effectively guide the modeling innovation of electric vehicles while ensuring the brand identity.
