Abstract
There are many design parameters affecting the performance of the stiffening ring, and it is difficult to obtain the optimal structure. By adopting parametric 3D modeling, this research optimized the design of seven key parameters: pad plate height, rib plate height, top ring plate thickness, rib plate thickness, bottom ring plate thickness, top ring plate width, and bottom ring plate width. Taking maximum stress, maximum displacement and minimum safety factor as three main constraints, 450 combinations were successfully optimized in 4034 combinations. The optimal quality of the stiffening ring was obtained while meeting strength and stiffness. The results indicated that the multi-parameter multi-constraint optimization design method is easy to obtain better-optimized performance, which has important guiding significance for engineering design and certain reference value for theoretical research.
