The orthogonal experimental design and response surface design were combined together to determine the combination of geometrical parameters to be designed of the bolt connection structure. The parameter modal and stress of bolt joint which had different geometrical parameters were simulated and analyzed by using APDL language. The response surface modal of maximum equivalent stress and mass were obtained. The optimal structural parameters of bolted joint were obtained by using the method of multi-objective fuzzy optimal design. The results showed that the maximum equivalent stress in the optimized bolted joint is lower 23.5% than that the original one and the mass of optimized one is lower 6.2% than that the original one,which offer reliable references to the structure design and the weight reduction of aero-engine casing.Read More
