The optimization method for the vehicle body assembly structure was studied in view of the overall performance of manufacture and assembly. A modified graph-partitioning algorithm was proposed to optimally divide the vehicle body assembly structure into a set of components. A side frame model for the typical vehicle body in white was built as an example, in which the structure geometry was transformed to a topological graph at first, then the topological graph was partitioned into a set of simply connected and independent sub-graphs with constraints of engineering meanings. The genetic operators in algorithm NSGA-1 were combined with the FEM analysis to calculate the optimal partition of the product structure geometry. The results show that the proposed method realizes the objective of optimal comprehensive performance for the vehicle body assembly structure. [ABSTRACT FROM AUTHOR] |
