基于形状文法的电动汽车设计研究

RESEARCH ON SHAPE DESIGN OF ELECTRIC VEHICLE BASED ON SHAPE GRAMMAR

为了在短时间内产生大量符合设计要求和技术要求的设计方案,提出了将形状文法应用于电动汽车形态设计的研究方法。首先,对电动汽车的典型性特征进行分析,然后提取最能体现电动汽车特征的前脸作为初始形状,对其应用一系列的文法规则,文法规则可以分为生成性规则和修改性规则,对应汽车造型特征的遗传和变异,对于具有品牌继承性的特征应用修改性规则变换,而对于创新性特征则可运用生成性规则进行添加和删除,同时指出具体的文法规则要根据相应的感性意象与约束规则进行确定。最后,以具有代表性的特斯x汽车为例进行验证,用语义差异法检验最终方案。形状文法可以适用于电动汽车的造型创新设计。

In order to produce a large number of design schemes that meet the design and technical requirements in a short time,the research method of applying shape grammar to the shape design of electric vehicles is proposed.First of all,the typical features of electric vehicles are analyzed,and then the front face which can best reflect the features of electric vehicles is extracted as the initial shape,and a series of grammar rules are applied to it,among which the grammar rules can be divided into generative rules and modifiable rules,corresponding to the inheritance and variation of vehicle modeling features.For the characteristics with brand inheritance,the modified rule transformation can be applied,while for the innovative features,the generative rule can be used to add and delete.At the same time,it is pointed out that the specific grammar rules should be determined according to the corresponding perceptual image and constraint rules.Finally,a typical Tesla electric vehicle is taken as an example to verify the final scheme with semantic difference method.Shape grammar can be applied to the innovative design of electric vehicle.
