Abstract

Based on the manufacturing history chain, a component’s macro residual stress is introduced to the subsequent assembly model. In the simulated method, the simulation cost is saved via mapping the bulk stress profile directly to the component compared to our previous study. It thus facilitates the finite element analysis (FEA) which takes the component location in blank and the thickness of blank as two influence parameters. The methodology is proved to be feasible by the validation experiment designed for a typical assembly structure from the aerospace industry. The results show that the bulk stress originating from material preparation affects the downstream large-scale assembly deformation. The investigation of this research helps systematically to improve compliant assembly precision.
