Abstract: Aiming at the modular design of the mechanical products having similar functions, multi specifications and being single batch inmanufacturing industry, the corresponding relationship was analyzed between the functional modules and the structural modules in the mapping process from the design domain to the demand domain, a coupled modular design method was presented. The structure combination relationship of the functional modules, the composition of the components and their connection relationships were analyzed on the basis of functional module division. The judgment criterion of coupled elements was determined and its detailed design method was given.Finally,the method was checked by the open-closed-mechanism for a space capsule door.The results indicate that the size between functional modules is adjustable aftercoupled design.A set of open-closed-mechanism for a space capsule door can be assembled on the doors with different diameters which meets the requirements of different center distances of two rotating modules.The influence of accuracy in thereassembly module interfaceis is avoided,the weight is reduced.
Key words: coupled modular design; coupled part; functional module division; the open-closed-mechanism for a space capsule door
