[ Abstract ] For solving the difficulty that the design wall thickness of the flat-plate head is too large, the
flat-plate head with stiffening ribs was proposed for improving the load-carrying capacity.
Based on the general finite element software named ANSYS, three numerical models of a
flat-plate head, a flat-plate head with rectangular-shape ribs and a flat-plate head with
T-shape ribs were constructed, respectively. Strength calculation of the flat-plate head were
carried out taking the role of rib into consideration, and an optimization program was also
developed for obtaining the optimal structure according to the ANSYS/Design OPT module
and APDL language. The optimization results showed that the wall thickness of the flat-plate
head with T-shape ribs was decreased about 59% than that of the flat-plate head, and the
weight of steel wa
