A simple and effective assembly sequence design method

Abstract

Abstract Assembly sequence design is a very complex problem in military enterprises due to the particularity of the military industry and the batch production. This paper proposed a method based on the existing expert knowledge and experience used to plan the assembly sequence. The method of assembly sequence design method is quantitative calculated based on five indexes, including assembly element benchmark index, assembly adjacency index, assembly process complexity index, assembly accuracy index, symmetry index of assembly primitives. And then construct geometric interference matrix to analyze the geometric feasibility of the assembly sequence. Finally, the procedure of assembly process sequence planning of flat-plate fuze is taken as an example to verify the effectiveness of this method. This method is suitable for the assemblies with less number of parts. It has been proved that this method based on the existing expert knowledge and experience, can quickly plan the assembly process sequence of parts.
