Design And Research Of Passenger Car Exterior Modification Kit Based On Reverse Engineering Development Mode

With the rapid development of the domestic automobile market in recent years,the number of automobiles is growing rapidly,and the automobile aftermarket is becoming more and more mature;In addition,due to the influence of the main consumer groups’ younger age and personalized demand,the single shape and function of the original car can no longer meet the different needs of different users.At the same time,with the change of relevant policies,the automobile modification industry gradually out of the original gray area.For countries with developed automobile industry,automobile refitting is one of the main development paths for automobile enterprises to transform and upgrade.However,the automobile refitting industry in China is still in the initial stage of development,which is characterized by unbalanced development among regions,lagging policies,slow progress of refitting technology and low level of specialization.In this paper,through literature research,data collection and other methods,on the basis of sorting out the types of automotive exterior modification parts,relevant laws and regulations,style characteristics and other knowledge,the legal modification scope is summarized.Secondly,market research and factory visits are carried out.Case analysis and questionnaire survey are used to analyze the user’s modification requirements.The requirements are classified hierarchically according to vehicle type,crowd,modification type and other elements,and the modification principles are summarized to improve the modification efficiency of user collaborative design.Thirdly,according to the hierarchical relationship of requirements,the logical framework of the database is sorted out,and the reverse development database model of exterior modification parts is constructed.Finally,based on the established database,the user demand data is imported.Through reverse engineering,collaborative design and other related theories and existing research results,empirical analysis is carried out;Through collaborative design,18 Tesla Model 3models are used for exterior modification design practice.The feasibility of reverse engineering development mode applied to automobile exterior modification is analyzed and confirmed.The methods and ideas of reverse development of exterior modification parts are summarized.Through the research,this paper thinks that it is feasible to apply the reverse engineering development model to the development of automobile exterior light modification kit.In the practice of reverse design for exterior decoration modification,the internal factors that trigger users’ modification motivation can be mined through hierarchical classification of users’ needs;Taking reverse engineering as a design method,with the help of exterior modification reverse development database,it can help designers to deduce new modification scheme from existing modification samples.Through a series of scheme samples,designers can better grasp the needs of users;Finally,through collaborative design,reverse engineering technology modeling,fast rendering scheme and other means,refine the user requirements,so as to achieve the purpose of strengthening the modification scheme.
