Based on the theory of elastic-plasticity and the reverse engineering of a certain model
the riveted fixture is optimized by calculation and numerical simulation through ordinary riveting method. The results show the optimum design of this fixture can greatly increase the uniformity of interference after riveting
make residual stress distribution more reasonable even come to an important assessment tools for detecting the amount of interference after riverting
and provid an important reference value for the aircraft manufacturing process optimization and assembly efficiency improvement
