摘要
当今,世界汽车技术水平不断发展,各种科技在汽车领域得到广泛应用,各种品牌中,同级别的汽车科技性差异并不明显,消费者在选购汽车时很难区别各种汽车在功能上的差异,基于此,汽车形态就成为其综合品质的重要组成部分,汽车车身形态研究越来越得到重视,因为不同的汽车车身形态彰显了不同的文化需求。当前,汽车车身形态研究的一个重要方向就是“汽车车身形态仿生设计”,这是利用自然界中生物系统和自然物质的形态、功能、色彩、结构等的丰富性、优异性,通过相应的设计手法,表现在汽车的形态之中,使之赋有仿生寓意。现有汽车造型理论中融入了仿生设计理念,使其理论变得丰富起来并且取得了创新发展。现代汽车车身仿生形态所传达的情感性与生命象征意义成为人们与汽车交互的精神所需,所以,仿生设计成为了汽车车身形态设计创新的重要手段。
     从汽车诞生时候起,仿生设计就开始融入到了汽车设计中,最初是无意识的应用到汽车车身形态设计中,但逐渐就开始了有意识的模仿。
     1、汽车车身设计基础理论研究
     汽车车身设计中形态仿生设计包括:仿生物“形”的汽车车身形态设计和仿生物“态”的汽车车身形态设计。汽车车身仿生设计中,生物的“形”和“态”设计是最重要的,他们也是相互依存,不可分割的,不能取其一,设计者通常是组合使用。汽车仿生造型经历了流线型风格时代、尾鳍型风格时代、梦幻型风格时代、肌肉型风格时代与现代型风格时代等。在汽车车身设计中还包括了色彩仿生设计、功能仿生设计、结构仿生设计、材料仿生设计、肌理仿生设计等重要的仿生设计手段。它们和形态仿生设计共同组成了不可或缺的汽车车身仿生因素。
     通过对汽车车身形态设计特点及原理的分析,证明了仿生设计在汽车车身形态设计中的重要性。通过汽车车身形态仿生设计历史脉络及作用归纳,证明了汽车仿生形态在历史进程中的重要作用与意义。通过对车身形态设计中仿生设计主要应用领域的归纳论述,阐明了能够使汽车车身形态设计最优化的关键因素。
     2、基于文化基因的汽车车身形态仿生设计
     在对文化基因认知基础上,通过汽车车身形态体现某特定文化意识形态的特定心理情感和审美反映。在研究文化基因仿生时,采用隐喻等方法对汽车车身进行综合设计表述。当今,世界各种品牌的汽车都在努力创造汽车“个性文化”,赋予汽车人类的精神文化与个性化语言。作者归纳出影响汽车车身形态的主要文化基因有:社会文化基因、民族文化基因、传统文化基因、企业品牌文化基因等。
     运用社会文化基因仿生设计可以生动的再现汽车文化,感受不同的文化背景设计理念的不同,感受人类文化不断进步所体现在车身上的不同文化印记。不同的民族文化基因也对汽车车身形态有着不同的影响,汽车车身形态的不同,反映了不一样的民族审美观。传统文化对汽车车身形态具有强烈的影响力,汽车车身形态不仅说明人与自然的和谐统一,更能表达传统文化带来的象征意义和传统人文价值。
     汽车车身形态仿生设计中企业品牌文化基因是形成汽车车身形态特征的各种重要企业文化要素的组合完成的,各种特征要素共同打造汽车品牌的形象特征。目前,一种汽车品牌下会有不同的汽车车型,它们在符合这一品牌主体特征的前提下,还要着力体现自己独特的设计特征来区别于其他车型,做到具有鲜明的识别性。
     通过对文化基因仿生类别的归纳和论述,强化了文化基因在汽车车身形态仿生设计中的重要作用,其中,在企业品牌文化基因如何应用到汽车车身形态仿生设计的具体研究中,论证了品牌文化得以能够更好的继承与发展的方法和手段。
     3、汽车车身形态一般仿生设计程序与方法
     现代汽车车身形态设计有标准的程序,就是市场调研-设计意向建立-草案分析-方案确立-程序调整-试制样品-样品评估-生产加工。由于设计理念、方式方法等的差异性,导致汽车车身形态仿生设计的程序与普通车身形态设计程序有很大不同,通过以上理论作为基础,深入研究了仿生设计在汽车车身形态设计中应用的方法,作者总结归纳其程序为,确定仿生目标——建立生物特征的概念认知——生物特征的记录——确定仿生设计概念——生物特征的产品设计转化——遵循美学规律设计等。可以看出,这是首先通过设计来源,进而通过仿生设计思维,利用设计转化而实现的设计方式。
     4、汽车车身形态仿生设计的认知心理
     认知心理是汽车车身形态仿生设计的理论支撑,形态仿生设计元素通过加工得到了独特的外观形式,向消费者传达出情感信息和文化信息。消费者运用视觉感知来了解形态,并做出判断。视觉认知存在三个特点:视觉二段式处理、视觉优先性、视觉内在图形。仿生形态使汽车有了生命活力,使整个形态充满张力,格式塔心理学的“似动”原理为汽车仿生形态的科学性提供了理论依据。人们对汽车仿生形态的认知理解,主要是人与汽车车身形态之间的情感互动的过程,设计师与消费者之间也利用汽车车身形态这一媒介来进行情感交互。那么,就需要在设计时把握好设计的感性和理性的运用,只有做到使其相互依存,相互制约,才能使汽车车身形态更好的传递情感。利用消费者对汽车造型的各种认知规律,明确消费者喜好,同时通过对其感知意象的提取,帮助设计师准确掌握消费者感觉与愿望,理解他们对产品的感受,从而来提升设计开发的成功率。
     通过认知心理学的相关理论为基础,深入研究了汽车仿生形态的视觉认知要素及所构建的体系,总结归纳出视觉认知要素,感性和理性的相互关系,情感交互原理,并深入研究了客户感知意向对汽车车身形态设计所具有的重要影响。
     5、汽车车身仿生形态特征的获取与表征
     汽车车身仿生形态获取与表征主要基于造型特征来实现的。构成汽车造型特征的主要元素有点、线、面。在汽车车身形态设计中,线形的设计表达是最主要手段,我们通过汽车的特征线来体现汽车的整体形态特征,实现仿生形态设计的获取与表征。
     通过研究实现汽车车身仿生形态的关键因素,进而对汽车主要造型特征线进行整理与归纳,取得了汽车仿生形态获取的有效途径。并利用形态联想,实现了汽车整车仿生形态特征的多元化表征。
     6、汽车车身形态仿生设计的语义表达
     汽车车身形态仿生的认知语义是以人的感觉和认知实践为基础,必须遵守的基本原则是人类认知科学,因此它有理性的特点,其语义表达式也应该是准确的和单一的。认知语义来表达的是汽车外观和材料性能及其使用模式相关的信息。关于对汽车的认知,使用者都会经历从疑惑到了解,从不会使用到熟练掌握的过程。所以,良好的认知语义应该降低使用者对产品的认知难度,缩短对产品的认知时间。
     通过概括总结得出汽车仿生形态的认知语义、情感语义、象征语义等。结合产品语义学的基本理论,并通过对汽车造型方法的影响的深入研究,提炼总结出产品语义学在汽车车身形态仿生方面的方法论问题。我们期望这一理论在实际工作中得到充分验证并能够为车身形态仿生设计的开展起到积极的指导作用。
     仿生设计一直贯穿于整个汽车设计的发展进程,它作为一种极其重要的设计方法在汽车设计领域里广泛应用。我们以汽车车身形态仿生设计为研究对象,阐述与其相关的理论知识,分析汽车车身形态仿生在基因学、认知心理学、产品语义学等视知觉领域中的具体表现。
     对于中国人来说,仿生设计是中国设计文化的一部分,有着非常广泛的应用基础,因此,我们要采用仿生设计作为突破口,积极寻找中国文化在汽车车身形态上的表现形式,努力使之成为中国汽车车身设计的有效手段。
Today, the world automotive technology is developing fast. All kinds of science andtechnologies have been widely used in the field of cars. Among these brands, thetechnological differences in cars of the same level are not obvious. So, it is difficult for theconsumers to find the functional differences between the various cars when they purchase amotor vehicle. Therefore, automobile form gets unprecedented attention. Different motorpatterns reflect different cultural needs. At present, one of the important directions onautomobile form research is "automobile body bionics design", which presents various forms,functions, colors, structures of biological system and natural substances in auto formsthrough corresponding design methods, and endows it implied meaning. Bionic designmakes a very important complement for the existing automobile modeling theory. EspeciallyIn today's society, people need more emotions and life symbols which are expressed by autoforms. As a result, bionic design will become an important method in the innovation of autobody designs.
     Since the birth of cars, bionic design has gone into auto design. At first, it was used inauto body design unconsciously, and gradually, it began to imitate consciously. Automobilebionic design experiences streamline style age, caudal type style age, fantasy style age,muscle style age and modern style age.
     1. Application of bionic design in auto body design
     Bionic design in auto body design includes: form designs which imitate the biologicalshape and those which imitate the biological form. In the auto bionic design, biologicalshape and form design is the most important, which are interdependent and can’t beseparated and chosen one. The designers usually use them in combination. Auto body designalso includes many important bionic designs, such as, color bionic design, function bionic design, structure bionic design, material bionic design, texture bionic design, etc. Thesedesigns, together with shape bionic design, compose the indispensable factors in auto bodybionics.
     2. Automobile body bionic design based on culture genes
     On the basis of cognizing culture genes, auto body form represents the specificpsychological and aesthetic reflection from specific cultural form. In the study of culturalgenes bionics, metaphor method is commonly used to express the integrated design on autobodies. In modern times, automobiles of various brands in the world are trying to create auto“individual culture” and giving autos human spiritual culture and personalized language. Themain culture genes that influence the auto body forms are social cultural genes, nationalcultural genes, traditional cultural genes, ect.
     Appling bionic design of social culture genes can represent auto culture vividly, telldifferent ideas from different cultural designs, and reflect different cultural stamps throughhuman culture progress. Different national cultural genes also influence the auto body forms.Different auto forms reflect different national aesthetics. Traditional culture stronglyinfluences auto body forms. Auto forms not only explain the harmony between man andnature, but express the symbolic meaning and traditional human values brought bytraditional cultures. Enterprise brand culture genes in the auto form bionic design are veryimportant in forming auto features which are made by all kinds of characteristics. At present,there are different auto forms from the same brand. While consistent with the main brandcharacter, these forms lay emphasis on its unique design in order to distinguish other formsand make a bright distinction.
     3. Common bionic design methods on automobile body forms
     There are standard procedure in modern auto body designs, that is, market research,design intention building, draft analysis, plan establishment, program adjustment, sampletrial production, sample evaluation and process production. Due to the differences in designconcepts and methods, auto body bionic design program is quite different from that ofcommon auto body design. Auto body bionic design program is to determine the bionicobject-----establish biological characteristic concept------record biological characteristics---- determine bionic design concept-----transform biological characteristic products design----follow the aesthetic law design. As can be seen, this design method is realized, firstly, by thedesign sources, then, by the bionic design thinking, and at last, by the application of designtransformation.
     4. Cognitive psychology of automobile form bionic designs
     Cognitive psychology is the theoretical support in auto form bionic designs. Byprocessing, bionic form design elements get its unique appearance, and convey emotionaland cultural information to the consumers. Consumers can know the forms by their visualperception, and then, make judgments. Visual perception has three characteristics: vision twosection processing, vision preference, vision internal graphs. Bionic forms make automobilesdynamic and teem with tensile force. The "like " principle in Gestalt psychology providesthe theoretical basis for the auto bionic science. Humans’ cognition to auto bionic forms ismainly through the emotional interaction between people and automobiles. Designers andconsumers also exchange emotions through auto forms. We should make use of consumers’cognitions on auto forms, definite consumers’ affections, and meanwhile, help designers tograsp the consumers feeling and desire accurately by fetching the perceptual image.We should also understand their feelings to the products, so as to raising the possibility ofsuccess.
     5. Acquisition and representation of automobile bionic forms
     The acquisition and representation of automobile bionic forms is mainly realized byform features. The main elements constituting auto form features are: point, line, and planar.In the designing of auto forms, liner design is the most important way. The whole formcharacter is transferred by the auto feature line, and realizes its bionic design and acquisition.And the plurality characterization of auto forms is realized by association.
     6. Semantic expression by automobile form bionic designs
     The cognition semantics of auto bionic form is based on human feeling and cognitivepractice. It must comply with the basic principles of human cognitive science. Therefore, ithas a rational feature, that is, its semantic expression must be accurate and unitary. Cognitivesemantics can reflect the relevant information of auto material performance and use methods. The users will all experience a progress to cognate the automobile, from doubt to understand,from ignorance to its usage to master it. So, cognitive semantics should reduce the cognitivedifficulty for the users and shorten the cognitive period to the products. Semanticexpressions of auto form bionics are: cognitive semantics, emotional semantics, symbolicsemantics, etc. We should combine theory and practice from the product semantic point ofview, and explore scientific form bionic design methods.
     Bionic design runs throughout the whole automotive design progress. As a kind ofextremely important design method, it is widely applied in auto design field. We use autoform bionics as our study objects, expound the relevant theoretical knowledge, and analyzethe specific performance of auto form bionics in the fields of genetics, cognitive psychology,product semantics, etc.
     To the Chinese people, bionic design is a part of Chinese design cultural. It has a widelyapplication foundation. As a result, adopting bionic design as a breakthrough, looking for thereflection of Chinese culture in auto forms, can form our own style, and become an effectiveway to vitalize Chinese auto designs.
