Abstract: Unlike traditional rigid body assembly, different joints configurations have different performance characteristics of dimensional variation. In order to deal with characteristics of sheet metal products, a systematic design method of adaptive joint optimization for sheet metal product was proposed. With this method, scheme design and evaluation of assembly process and structure were conducted during the conceptual design process so as to achieve online adjustability of final product dimension. Adaptive joint design rule was brought forward and mathematical model of joint optimization was constructed. Genetic Algorithm was employed to obtain solution. This method has laid foundation for improving the final dimension precision of product and reduce design experiments rates.

Key words: joint optimization, sheet metal product, assembly sequence, assembly model
