Research On Modeling Design Of Electric Logistics Light Truck Based On Kansei Engineering Theory

With the rapid development of China's economy,environmental pollution is becoming more and more serious,which has seriously affected the living environment and social development of the people.In recent years,in order to promote new energy vehicles for energy conservation and environmental protection,the development of new energy vehicles can not only get the support and protection of national policies,but also play a positive role in the development of environmental protection.Among them,the electric logistics light truck as the main transportation means of the logistics industry,the sales prospect is very optimistic.At the same time,people also pay more and more attention to the appearance design of electric logistics light truck.Therefore,the purpose of this thesis is to use the design principle of inductive engineering and fuzzy comment method to study and explore the aesthetic law of light truck modeling in electric logistics.Through the interaction between designers and consumers to obtain their emotional needs,"people-oriented" design ideas into the electric logistics light truckmodeling design.It can not only meet the Kansei demand of consumers,but also improve the comprehensive experience of electric logistics light truck.Product design tends to be reasonable,adapt to the rapid development of the market and improve market sales.Therefore,this paper mainly do research from three aspects:(1)Based on the theory of perceptual engineering and from the perspective of consumersundefined perceptual demand,this paper studies the design of electric logistics light truck as a practical case.Firstly,it collects and selects the perceptual vocabulary and the modeling sample pictures of electric logistics light truck.After screening the sample pictures according to different styles for classification extraction.Then,the semantic image space is established by using the SD scheme combined with the Richter 7-point scale,and the design elements are selected.Finally,through the emotional degree of interest survey to collect relevant data for analysis.Let designers and consumers establish contact,understand their aesthetic.(2)Quantifying the perceptual semantics of consumers,analyzing the relationship between perceptual image and design elements,and helping designers to determine the direction of styling design.Finally,the perceptual image of consumers is combined with the design elements to guide the design of several electric logistics light truck modeling schemes which accord with the consumersundefined perceptual needs.(3)The concept of fuzzy evaluation method is expounded.The perceptual quantitative evaluation of two design schemes of electric logistics light truck is carried out by using fuzzy evaluation method,and the scientific quantitative basis and reference are obtained.At the same time,further optimization and improvement of the design scheme are carried out.Based on the above analysis and research,this paper uses qualitative and quantitative analysis methods to improve the modeling of E-series light truck.The feasibility of applying the inductive working theory and the fuzzy evaluation method in the field of automobile modeling is put forward,and the reference suggestion is provided for the design of the light-card design of the large-transportation electric logistics.
