The Research And Applicationon Of Yacht Design Based On HBM In Bionics

In the field of product design, view from the time dimension, the human civilization growing up from savagery is based on the imitation and adaptation of the laws of nature.extent, bionic design theory is applied to household items to various products design of the military. View from ship design , from bamboo raft imitating leaves to yacht design imitating variety of birds and fish, it reflects the extensive use of bionic design. Bionic design is a perceptual design method from the emotional design combined with cognitive psychology theory. It has a certain vagueness and ambiguity in cognitive semantics . Therefore, this paper studies several links of bionic design process from the perspective of topology, uses HBM theory and topological weight calculation methods etc, adds geometric elements in the selection of biological characteristics and prototype , and hopes to get a more rational approach .Finally, the method from research is applied to yacht ’s bionic design.This thesis makes a detailed analysis of the theory of bionic ( the meaning, principle, classification of bionic design , etc.) . Based on the connotation and extension of semantics, cognitive psychology, graphic coding, topology and other related theoretical research, this paper analyzes all aspects of bionic design , focusing on two areas such as principles of feature extraction and features predigestion .Then the paper creates a topology model with biological prototype as an invariant, characteristic lines and position relationship between the graphic form framed by characteristic lines as avariables,and study biological features extraction method of bionic design in this model.Finally, through introducing Sunbird yacht bionic design process , it tests these methods and principles used in bionic design.
