Modeling Gene Of Intercity Train Based On Perceptual Image Research And Application

With the continuous improvement of China’s high-speed railway network,railway passenger transport gradually develops from cross regional trunk line passenger transport to small-scale,terminal and within the city circle;at the same time,with the continuous development of the city,the concept of intercity circle and city circle is gradually improved,and the demand for Intercity or within the city circle is growing;with the introduction,digestion and absorption of time,China’s high-speed trains have experienced rapid development We have also launched the Fuxing EMU series with Chinese characteristics,but we still need to further study the commuting in the city circle,the connection of high-speed trains,and the development and pedigree of intercity trains.On the other hand,the user’s requirements for products have also changed from the basic product function requirements to deeper emotional needs.As a large-scale transportation equipment used by users frequently,intercity trains should not only consider the function of providing support,but also be guided by users’ perceptual needs and support each other to form a good public image in the design process.Based on the method of Kansei Engineering and the theory of modeling gene,this paper studies the relationship between modeling gene and perceptual image of intercity train,which is an urgent product to be developed and optimized.Based on the expression of modeling gene based on perceptual image,this paper summarizes the pedigree design optimization ideas of intercity train,so as to provide new design ideas and innovative methods for the research and redesign of high-speed train modeling gene in China.First of all,through the analysis and Research on the relevant methods of modeling gene and perceptual image,combined with the theories and methods of product shape gene level theory,perceptual image mapping expression,quantitative class I and other related fields,this paper puts forward the design research process of this topic;then,through a large number of data collection and intercity train modeling gene research,it analyzes the design of many countries Based on the representative modeling information of intercity trains,the modeling characteristics of intercity trains are analyzed from two scales.The modeling genes are structured,analyzed,extracted and expressed through shape grammar and gene feature line.The explicit expression,recessive expression and product gene perceptual image are proposed.The relationship between modeling genes and perceptual image of intercity trains is clarified,As well as the necessity of intercity train shape gene research.Next,according to the previous research on the shape gene,we construct the intercity train shape gene sample space,and then extract the most representative gene Nine groups of image adjectives are used to construct the perceptual image space;the quantitative relationship between the model gene sample space and each perceptual image space is obtained through semantic difference experiment,and the mapping model is established by using the theory of quantification;the experimental results are further analyzed and studied,and the perceptual image of the model gene is predicted,so as to guide the pedigree design of the new generation intercity train.Finally,according to the prediction value provided by the mapping model,the representative shape gene is selected to design the appearance of the new generation intercity train.The rationality of the scheme is verified by using the independent sample t test,and the reliability of the model is proved.
