The variance of stress about particular points that situate on the edge where maximum stress point locates as the object function, we introduce complex method to optimize the position of exterior load point about pylon along the voyage direction and the angle between anti-swing stop and right-and-left symmetry plane about pylon under the determinate loads. We also compare the unoptimizable stress curves with the optimized to validate the feasibility and correctness of the optimization method.
