拓扑优化理论在二维平面闸门设计中的应用

拓扑优化又称为结构布局优化,其主要目的是致力于寻求优化结构的某些性能或减轻结构重量的途径。随着形状优化和尺寸优化设计的不断成熟与完善,拓扑优化逐渐成为结构优化设计的研究热点与难点问题。利用连续体结构拓扑优化理论,对结构复杂的水工平面闸门进行研究,并通过对优化结果进行拟合,进行结构变形分析与应力校核。结果表明结构应力分布均匀,能够更好地发挥各部位材料的最佳性能,验证了拓扑优化理论在水工闸门中应用的可行性与优越性。

Application of topology optimization theory in two-dimensional plane gate design

The basic idea of topology optimization,also known as structural layout optimization,is a design method that seeks for the most optimal distribution form of structural stiffness in design space or the best way to optimize some structure behaviors,reduce the structure weight and pass load.With the maturation and the improvement of shape-size optimization design in structure,the topology optimization has become the hotspot and the difficult problem in structural optimization design research.We attempt to intr...
