摘要
Abstract
Hydraulic hoist is used for the open and close of the lower head work gate of ship lift in Three Gorges Project. The hoist frame is safe if the traditional design method is applied, but it has heavy self weight. The structure of hoist frame was performed static analysis using the finite element software to obtain the distribut ion of equivalent stress. In order to improve the initial design of hoist frame, the topological optimization of structure was performed. Based on the objective function of self weight, the material distribution pseudo-density of the structure was obtained from the maximum structural stif ness with 25% decreasing of volume. On the basis of to-pological optimization results and requirements for manufacture, the frame structure was improved by the measures such as local struc-tural change, adding or removing reinforcing ribs, and modification of plate thickness. The modified results can not only meet the require-ments of strength and stiffness, but also decrease the self weight effectively.关键词
