Research On Geometric Modeling Based On LEXUS Brand

Automobile body shape-designing is an essential part of car's whole development,and on this basis,aesthetic modeling and aerodynamics determine the development tendency of automobile body shape.In design and development of automobile body shape,we need to consider the beauty of appearance,the convey of emotion,the ethnic feature,brand consistency and something else about visual level.As for the styling features of the brand,how to impact customers' cognition and maintain emotion has theoretical and practical significance for brand's success.Topic selection in this paper is derived from the analysis of design examples,which is focused on two basic theoretical points: the first,the shape cognition of automobile body shape-designing is the bridge of designer and customer's communication;the second,the design of automobile body shape is a multidisciplinary intersecting complex discipline,which is calling for design knowledge,engineering knowledge and design process.The former two points are the main ideas of this paper,which are necessary to know the cognition,expression of brand geometric shape and creativity which is based on the reasonable engineering knowledge level.The study uses “Case analysis”,“Aesthetic analysis”,“Simulation verification” to study the main points.On the basis of the abundant literature studies,this study addresses specific issues,puts forward the theory form,research value and creativity.As the development of computer science,wind tunnel experiment costs a lot,so computational Fluid Dynamics(hereafter referred to as CFD)plays a very important role.Therefore,this paper is morphological simulation research based on CFD.This passage is mainly focused on the example of improved geometric shape design,using grid partition,calculating analysis to provide aerodynamic analysis and summary of data support for the example of improved geometric shape design.The study contains: this passage takes the geometric shape modeling study of Lexus brand as a core,using four aspects to demonstrate,one aspect to express design cases.Part of these constructs the whole with firm and abundant data.First of all,analyzing research objective and present situation;second,analyzing basic theoretical study of automobile body shape;third,analyzing systematic method study on automobile body;fourth,summarizing adaptability study of geometric shape used on automobile body;fifth,analyzing the examples of automobile modeling design and the study of CFD.There are four innovation points in this paper.First,the passage summarizes and develops methods of geometric shape and analyses evolution process of geometric shape and the expression of final shape;second,the passage analyses cognitive elements of Lexus ‘ shape,puts forward that geometric shape belongs to cognitive to form visual intuition;third,the passage takes Lexus as a main case to analyse applicability relationship on geometric shape,based on the practical examples and constructs excellent geometric form theory system;finally,the passage studies the concept of local stereoscopic used for improvement and design of RC,and puts forward geometric shape model based on the application of CFD.This passage explores the trend of automotive modeling design nowadays and defines the future development direction,distills design methods and ideas of automobile modeling based on geometric shape.The passage also provides abundant argumentation material for the future development of domestic automobile modeling by constant verification the excellent cases of foreign geometric shape applied on automobile modeling.
