The Application Of Coach Body Modularization Design

As people’s living standards improve, travel comfort, travel and tourismneeds and the accelerated process of urbanization development to thedevelopment of China’s coach industry has brought new developmentopportunities, it also brings new challenges. How high-quality, short productionto meet customer demand coaches, became China’s coach industry need tosolve the problem.Modular design is a product of customer needs functionality, appearanceparameters were analyzed based on the design of a series of modules, throughdifferent combinations of modules and transformation, to achieve the productconfiguration adjustments and modifications designed to meet user the diverseneeds. coach industry has a typical small quantity and variety, a high degree ofcustomization features, this feature determines the coach body design ismodular in design is imperative.This paper studies the system modules, modular theory, and modularproduct design methods, based on the state of different products on modularproduct design process into a new product’s modular design, variant product ’smodular design and existing products the modular design of three categoriesimproved. For the purchase of passenger groups using fuzzy clustering analysismethod customers are classified, for different customer groups using AHP todetermine the product spectrum.Modular design approach to a section dedicated school bus body as amodel for a module specific division, get six one module twenty-two twomodules, and each module is the interface between the methods wereanalyzed, get two connections. In order for the module division objectiveevaluation of the results, using a simple, intuitive scoring method to divide theresults were evaluated. Finally, CAD technology is based on parametric designmodule four forms were discussed, so that the advantages of the modulardesign can be fully realized. Through the modular design of the school bus has been put into massproduction, the actual production process was generally body structure is simple,versatile, good quality easy to guarantee. In the school-based follow-up carmodule division has developed two8m,10m special school bus, designed toshorten the development cycle time for three months, tooling investmentreduced by two thirds, established from7m-10m complete school bus platformfor enterprises to create a considerable economic benefits.
