大型水闸三角闸门的优化设计

摘要:
三角闸门以往的优化设计往往是将闸门简化成为平面体系,或者对其各个构件分别进行优化.前者忽略了三角闸门作为一个空间体系各构件之间的联系,而后者各个构件的最优并不能等同于整体结构的最优.按照三角闸门真实的三维情况,利用APDL语言对三角闸门有限元模型进行二次优化,融合了有限元法结构分析的准确性与优化方法求极值问题的高效性,成功地解决了三角闸门的三维优化问题,为三角闸门结构的优化设计提供了一种有效方法.

Optimum design of a large-scale sector gate

Abstract:
Generally, the optimum design of a sector gate is simplified as a planar system, or only to optimize various components. The former ignores the link between each component for the sector gate as a space system, while the latter, the optimization of various components, cannot be equivalent to the optimization of the whole gate structure. In this paper, according to the real three-dimensional situation of a sector gate, we use ANSYS Parametric Design Language(APDL)to re-develop the finite element model for the sector gate. This method can combine the accuracy of FEM structural analysis with the high efficiency in solving extreme value problems, so it resolves the sector gate′s three-dimension optimization problem successfully.
