Research And Application Of Modular Design Technology Of Automobile Chassis

With the development of economic rapidly,market demand changing constantly,manufacturing of users tend to be more customized,personalized,diversified needs,This is a key feature: How to respond to market of demand quickly in the manufacturing is a effective way to maintain competitiveness incentives competitive environment;on the other hand,The traditional design method cannot meet the curre nt complex and volatile market demand,The enterprise urgently need to find a viable and efficient design method to approach to meet its changing customer needs,There is a profound impact of modular design research and application of the method for manufacturing enterprises.The article is based on automobile chassis products,with modular design research and analysis,the specific contents are as follows:(1)Analyze the modular design theory of existing,Put forward a Module division method is based on o f functional decomposition;establish a customer demand indicators of analysis model and based on this model to calculate relative importance,determined the relative importance of the right indicators value,consistency checking,Finally,Utilize QFD techniques to determine the chassis product line spectrum.(2)It is based on the spectrum chassis product line that the chassis structure and function is decomposed,in accordance with the principle of functional independence,the total chassis functions are broken down into multiple sub-functions,and build chassis of product function module system finally,for on this basis the method has been studied for solving functional modules.We studied the correlation between the modules as well as the calculation method Calculation method focuses on hierarchical clustering.(3)On the basis of the functional module system,in accordance with the calculation method of correlation between sub-functional elements to solve,and the formation of affinity matrix,using MATLAB software programming function,the 16-order correlation distance matrix is solved,and then get chassis module division programs and the eventual establishment of chassis product family structure model.(4)The chassis module analyzes code design and data management,analysis of the data storage method module,while a fuzzy pattern recognition method based on retrieval module;design of a major three-part code bits 51 OPEN type of coding system,and gives examples of coding explain.Through the modular design of automotive chassis analysis and research for enterprises to implement the platform,modular offer some insight,preparation coding system makes computer-aided modular design provides the premise and foundation.
