Multi-objective-driven Morphological Bionic Design Of Greenhouse Concept Electric Tractor

China as one of the agricultural powers,agricultural machinery products have always played a role in the development of the national economy.The diversified development of agricultural economy promotes the emergence of greenhouse and other facility agriculture and becomes the key to increase agricultural income.In view of the specific operating environment of greenhouse,traditional agricultural machinery has the disadvantages of heavy fuselage,low operating efficiency and high environmental pollution,which can no longer meet the operating requirements of greenhouse.At the same time,with the intensification of the homogenization of functions and technologies and the increasingly fierce market competition,the competition between agricultural machinery brands not only stays in the competition between product quality,performance and price,but also puts more emphasis on the characteristic and beautiful and comfortable appearance design features,and shapes the visual image in line with the product demand.This paper based on the national key research and development plan:coupling double motor drive electric tractor integrated to create and experiment examination(2016YFD0701005),completed in the early stage of the production plan,should be the brand request,hope to finish a greenhouse concept tractor morphological design,aimed at improving brand identification and innovative,for the following brand modelling to provide new ideas and new direction.Due to the nature of "take" the bionic design of agricultural machinery products:"natural farming" design technique and image has a very high in particular,and the bionic design method validation by scholars in the agricultural machinery product design has the characteristics of high efficient and feasible,so this article choose appearance bionic design as essay writing and the practice of design guidelines,according to the characteristics of target products have been identified at the same time,choose the appearance of "top-down" bionic design process.According to the present appearance bionic design of product shape design aim and existing problems in the biological sample selection,this article will perceptual image and product form bionics design theory was applied to the combination of the greenhouse in the conceptual design scheme of the tractor,the four main parts as follows:the first part,introduces the concepts and greenhouse tractor tractor,perceptual technology and multiple targets image and product form bionics design research present situation and the knowledge framework.The second part,in order to determine the shape of the concept of greenhouse electric tractor design goals,using the clustering analysis method,the SD questionnaire analysis,multiple regression analysis and SPSS software,combined with the brand identity,user image,social situation,more than three targets dimensions identified six product image adjective,clear the purpose of product form bionics design direction.In the third part,in order to efficiently and accurately screen out the biological samples that conform to the multi-objective image of the product,the representative biological samples were determined based on the semantic difference method.In the fourth part,based on the selected biological samples for divergent thinking,on the basis of following the relevant design principles of bionic design of product appearance,through feature line extraction and other design techniques,the bionic design scheme of greenhouse concept electric tractor appearance in line with the multi-objective image was completed.The operation mode,operating system,operating device and interactive interface of the concept tractor are designed.Through the research on the bionic design of the multi-objective driven greenhouse concept tractor,the design efficiency of agricultural machinery product design is improved and the image positioning of agricultural tractor farming nature is met,and the design expectation of the greenhouse concept electric tractor is fulfilled,which provides new ideas and new directions for the follow-up tractor design of the brand.
