Research On Passenger Vehicle Side Shape Design And Structural Lightweight

With the development of industrial technology,Passenger vehicles have become the most preferred means of transportation for people.To meet the personalized needs of consumers for the side wall shape of passenger vehicles,the side wall shape design of passenger vehicles has become the focus of the development and research of Passenger vehicle enterprises.At the same time,the green design of energy-saving and emission reduction has always been a hot topic in the structural design of passenger vehicles.Therefore,the realization of the lightweight side wall structure of passenger vehicles is the key to this paper.The main research contents and techniques of this paper are as follows:(1)Discuss related theories of passenger vehicles side modeling design,study the influence of characteristic elements and modeling forms of passenger vehicles side modeling on passenger vehicles modeling style,and explain how feature lines can not only reflect the design connotation of passenger vehicles side modeling,but also reflect the side structure information based on lightweight considerations.The application of bionic design and parametric design in passenger vehicles side shape design is studied.(2)Analyze the specific research methods for the lightweight of passenger vehicles side structure,study the methods to achieve the lightweight of passenger vehicles side structure from three aspects of material,process and structure optimization,and make a comparative analysis of the advantages and disadvantages of each method,and apply reasonable methods and means in the lightweight design of passenger vehicles side structure.(3)On the passenger vehicles side surround modelling design research,the target users,using the environment position,body size and structure performance and extract about design intention and side outline feature,vocabulary study passenger vehicles side surround modelling characteristic concept sketches,and through 3D software Rhino passenger vehicles 3D model,and apply colours to a drawing gives its rendering.(4)for the passenger vehicles side surround modelling scheme,the structure of passenger vehicles side circumference of component design,develop with laser tailor-welded hot stamping molding method of one-piece processing technology,combined with the theory of blank design method,size optimization of blank shape,for lateral confining structure performance differences of different location,choose high strength steel materials,advanced So that the side structure to ensure safety under the condition of lightweight.Then according to the lightweight requirements,formulate reasonable material thickness and material location layout,formulate the hot stamping processing process and specific parameters,in order to improve the structural performance strength,and finally realize the lightweight design of the side structure.This paper summarizes the relevant theories and methods of passenger vehicle side wall modeling design and side wall structure lightweight and applies them to design practice based on the above methods While ensuring that the appearance of the side wall of the passenger vehicle conforms to the public aesthetics,it also realizes the lightweight of the internal side wall structure of the passenger vehicle,reflecting the unity of the formal beauty and functional beauty of the passenger vehicle.
