【Abstract】 This paper analyzes the characteristic and the key technology of concurrent engineering; including design process, the intergrated framework of PDM and design for assembly, and research for the relationship between product design and assembly process and the frame of design for assembly. On the basis of the above theory, a kind of concept of system framework based on design for assembly is put forward and apply to some processes on the support of software systems-CATIA, DELMIA. Those processes includes concept design, geometry modeling, process plan and process simulation. Finally, we present the application of car drive panel assembly by use of DFA in concurrent engineering.更多还原
