In the “last mile” transportation and distribution of the city,the convenience,safety and adaptability of pure electric logistics vehicles constitute a unique advantage.More and more urban distribution chooses pure electric logistics vehicles as transportation tools.At the same time,enterprises and users are paying more and more attention to the design of electric logistics vehicles,and put forward higher requirements for the innovative design of logistics vehicles.In many modeling methods,morphological bionics can provide infinite inspiration to designers,applying the shape of bionic objects to the overall or partial design of car styling,which can enhance the visual impact and aesthetic characteristics of car styling,reflecting the rich Culture,fun and emotional intentions enhance natural harmony and affinity,shorten the distance between man and nature,satisfy the psychological appeal of the public to return to nature,and interpret the design concept of harmony between man and nature.However,due to the sensuous and fuzzy design features of morphological bionics,this paper attempts to introduce topological correlation theory,such as topological structure,topological relationship,topological weight andtopologicality,into the morphological bionic design,and analyze and construct the morphological characteristics of bionic objects.To control the entire process of bionic design of electric logistics vehicles.The main goal of this paper is to expand the theoretical study of bionic design of automobile form and the specific design method of rich form bionics.Therefore,this paper mainly studies from three aspects:Therefore,this paper mainly studies from three aspects:(1)Analyze the concept of bionic design: introduce relevant definitions and concept theory,determine the corresponding value system;analyze the design context of the shape bionics in the history of automobile design,and understand the characteristics of bionic design of automobile forms in different eras;from the whole and local parts of the car The specific application of the morphological bionic design is analyzed and researched,which lays a foundation for the subsequent bionic design of the van electric logistics vehicle.The basic process of the bionic design is determined according to the general process of product design.(2)Analysis of the relationship between topological properties and bionic design of automobile form: introducing the concept of topological properties,linking the morphological study of topological properties with the morphological analysis of bionic design,analyzing the cognitive methods and cognitive features of topological morphological cognition,and Inspired by the design of automobile shape;analyze the relevance of topological andmorphological bionic design in research tasks,research objects and research methods,determine the constraints of topological correlation theory on the bionic design of automobile form,and analyze and summarize the different constraints,and then The constraint method is combined with the basic flow of the bionic design of the van-type electric logistics vehicle,and the specific constraint method of the topology in the morphological feature cognition and extraction process of the bionic object is defined.By introducing the common bionic object-shark as the analysis object,the analysis and verification constraint method is analyzed.(3)Analyze the actual design case: Combine the modeling characteristics of the van-type electric logistics vehicle,and carry out the bionic design of the van-type electric logistics vehicle under the topological analysis.By determining the bionic object--the tiger,analyzing the morphological characteristics of the tiger and extracting the main topology of the tiger morphological structure Relationship,simplification and transformation of the main feature structure relationship to determine the basic contour of the van electric logistics vehicle model,design a van-type electric logistics vehicle bionic shape.Based on the above analysis and research,the relationship between topological and morphological bionic design is summarized,and the specific constraint method of topology in the bionic design of van electric logistics vehicle is analyzed: analyzing the topological structure of biomorphic features,establishing the topological relationship of feature structure,and calculating the topological relationship.Weight,parameterized constraint form bionic design process;subject practice proves the importance of topological properties in morphological bionic analysis.Through the rationalized topological property analysis method and the theoretical research of rich form bionic design,it provides a new idea for the bionic design of van electric logistics vehicle and broadens the channel of modeling design method.
