Research On Modeling Design Of Electric Logistics Vehicle Based On Formal Beauty Law

With the change of people's online shopping mode and the rapid development of animal streaming industry,the problem of energy shortage and environmental pollution is becoming more and more serious in China.Therefore,our government has issued relevant policies and started to vigorously develop the new energy industry.As a pillar industry of transportation industry,the new energy logistics vehicle is strongly supported by our government.The advantages of low cost and zero emission electric tramcar in the field of urban distribution are constantly highlighted,and more and more attention has been paid to it,and the advantages and disadvantages of its shape affect the beauty and appearance of the city.Therefore,the shape design of electric logistics vehicle is more favored by consumers and enterprises.At this stage,because most of the electric logistics vehicles in our country are relatively single in shape,the details of design can not be well grasped from the aesthetic point of view,resulting in low overall shape identification.The shape design of electric logistics vehicle should be guided by "beauty of shape" and emphasize fashion and harmony in appearance design to increase identification.The law of formal beauty is the aesthetic standard of all artistic activities.Electric logistics vehicles should not only satisfy the inherent functions,but also highlight the advantages of modelling in the market competition.Therefore,it is necessary to combine the appearance design of logistics vehicles with the law of formal beauty.The appearance design of electric logistics vehicle should follow the principle and law of beauty and create its unique style.In this paper,the relationship between automobile design and the rules of formal beauty will be discussed in depth,and then the methods of electric cart modeling based on the rules of formal beauty will be concluded,so that the design conforms to the aesthetic principles.At the same time,this paper will also discuss the application of NURBS curve in the design,and provide more rational guidance for the later design.Therefore,this paper will study from the following two aspects:(1)Theoretical research: Introduce the general rules and rules of formal beauty and the constitution rules of modeling elements;and analyze the application of formal beauty rules by combining case studies in product design,furniture design,graphic design,architectural design,automobile and other fields to grasp the general rules and modeling methods of formal beauty.At the same time,the application of NURBS curve in design is studied,and the modeling method of NURBS curve is grasped.(2)Case analysis: This paper collects the latest concepts of electric truck shape designed by various manufacturers,and analyses the application of formal beauty principle in its shape design,as well as the future design trend of electric truck shape,and summarizes a set of modeling methods that conform to the current public aesthetics and the future design trend.Then,an electric logistics vehicle is designed by means of symmetrical balance,harmonization,differential contrast,gradual change and analogy.Finally,the results will be tested and evaluated by the formal beauty rule and questionnaire.Based on the above analysis and research,this paper uses the formal beauty rule and NURBS curve to conceptually design the electric tramcar,which makes the final design more in line with the current public aesthetics,more integrated and more rational.The application of its theory also provides more rational guidance for the following design practice.
