Research On The Application Of Parametric Skin Design In Automobile Shape Design

After more than 100 years of development,the automobile industry is undergoing subversive changes.In China,car sharing,electrification,networking and intellectualization are developing with a relationship of mutual promotion and integration.The "new four modernizations" have a great influence on the innovation of automobile form,and the parameterized skin technology,as one of them,plays a great auxiliary role.However,the parameterized skin automobile released by many automobile enterprises did not make innovative design in line with the times,but grafted the new technology in the existing models or modifications,such car modeling can not meet the expectations of users,nor better inherit the brand culture.It is the responsibility and mission of contemporary designers to grasp the image cognition of automobile modeling,apply the parameterization to the design of automobile shape,and design the parameterized skin automobile in line with the user's time cognition.The user cognition and brand culture inheritance of car shape are two important directions of parameterization and car shape application matching.Aiming at the application matching of parameterized skin in automobile shape design,this paper,from the perspective of cognitive psychology,analyzes the problems,design elements and application methods of parameterized skin in automobile shape design with the clue of "four elements" analysis method,auxiliary image cognitive matching method and shape analysis method.The whole research process is divided into five stages: acquisition of application matching problem,design direction of brand culture aiming at the problem,decomposition of elements in matching application,matching database of cognitive matching and case verification.First of all,in the first and second chapters,the definition differences among parameterized,parameterized skin and parameterized technology are described,and the theoretical research status of parameterized and automobile design is analyzed;then,the theory and research methods of parameterized skin and automobile modeling cognition are combed,and the existing cases of parameterized skin automobile shape are collected and sorted out,and the existing application matching is summarized Question,put forward the design direction from the perspective of brand culture.In thethird chapter,the design elements of parametric skin and car shape are decomposed.Through simplification and abstract expression,the modeling elements in application matching are decomposed.In the fourth chapter,based on the cognitive theory of automobile modeling image,the application matching research of parametric skin and automobile shape design based on user cognition is carried out,in order to obtain the feature matching database of parametric skin automobile shape design.In the fifth chapter,in order to verify the research results,take the shape adjectives obtained from the research as the design origin to diverge,look for the bionic prototype of Dongfeng automobile brand culture,extract the parametric skin and the feature elements of the application position in the shape feature matching database through the shape adjectives,and combine the parametric shape features obtained from the research to carry out two parametric skin automobile modeling design practices ?This paper collects and sorts out the application of parameterized skin in automobile shape design,and carries out the application matching research of parameterized skin and automobile shape design based on user cognition.This paper studies the mapping relationship between parameterized car modeling adjectives,parameterized car modeling and parameterized skin modeling,constructs parameterized car design process,provides basis for parameterized car modeling design,and provides reference for automobile enterprises to design parameterized cars.
