| Graceful shape is one of the attractions when consumers choose automobile products. As a result, in order to enlarge shares, each auto enterprise regards appearance of automobiles as a critical means of marketing competition. The designer always takes a very keen interest in its body proportion. The fine modeling or appearance requires reasonable and aesthetic properties of proportions among all components and parts. So we are supposed to develop a set of scientific standards to make judgement and quality of automotive modeling design will be improved as a whole. The reasonable assessment which should be specific to proportion level can't be limited to its appearance.The significance of this subject is to study proportion index factors in automotive modeling and their impacts on style quality. We will make use of fuzzy math comprehensive evaluation theory and analytic hierarchy process method to make further research into how human brain feels about automotive appearance proportion, which will generate specific evaluation index factors of fuzzy evaluation concept to offer reasons for appearance designs that are welcomed by people. By studying the impact indicators proportion automotive styling elements designed to impact on car styling quality evaluation results obtained aesthetic evaluation is the most important indicator element of car appearance evaluation.A fuzzy evaluation concept of "aesthetic evaluation" as the evaluation based on intuition, using fuzzy comprehensive evaluation theory and AHP to further establish the "aesthetic evaluation" of the specific evaluation elements: "modeling language, color, language and material texture." On the appearance of the car body proportions fuzzy comprehensive evaluation research, evaluation by research aesthetic elements will be one of the "modeling language" as the primary evaluation factor as an entry point for auto aspect ratio analysis and modeling language divide, and the car Exterior styling language aesthetic evaluation to quantify the proportion of three two evaluation factors, 10 three evaluation factors.Established automotive styling aesthetic aspect ratio base model evaluation.Thesis "car front face" aspect ratio modeling "aesthetic evaluation" to establish a car front styling aesthetic proportion fuzzy comprehensive evaluation model for a specific instance. According to the model requirements, through inductive research on existing models of car market in the form of proportional modeling language for modeling proportion of Automobile front face, which is three more quantitative evaluation factors stars 14 four evaluation factors specific targets.In order to evaluate the level of study where the levels of weighting coefficient factor and 14 four evaluation factors(ie specific quantitative targets) for "car aesthetic trends- atmosphere" of membership, selected market research ways to get the user's recognition data, according to theselected frequency to determine the relevant factors are weighting coefficients and associated quantization factor membership. Finally, the final evaluation results obtained by calculating the fuzzy comprehensive evaluation method of multivariate mathematics.The paper analyzes the aspect ratio for the car front face modeling fuzzy comprehensive evaluation study, a systematic study of the evaluation factors of car appearance front face, the establishment of evaluation model.Owing to quite a wide choice of automobiles, when taking the industrial evaluation system into consideration, a lot of market researches of model characteristics, customer demands and fashion trends in various types are done to form a complete set of scientific evaluation system. So in this subject, the aesthetics study on proportion of automotive modeling design is provided with general applicability.Fuzzy evaluation method for guiding cars exterior design and predict the market reflects the new models listed have a certain reference value. |
