Assembly sequence planning of automobile body components based on liaison graph

摘要

Purpose - This paper presents an algorithm for the generation of mechanical assembly sequences. Design/methodology/approach - The algorithm employs an adjacency matrix, and uses three different mathematical patterns of subassemblies to generate automatically all geometrical feasible assembly sequences. Findings - This algorithm cannot only generate automatically all geometrical feasible assembly sequences but also reduce the number of sequences. Originality/value - Assembly modeling is more completed than that of previous research; the method is able to automatically generate all possible assembly sequences and be implemented easily with program; and this paper makes use of exact mathematical equations describing every subgroup of the three-subassembly patterns.
