拱坝二维水平拱圈的拓扑优化研究

Study on the Topology Optimization of 2-D Horizontal Arch Ring

利用均匀化拓扑优化方法,根据拱坝特点,以体积最小为目标,对拱坝的体形优化进行了探讨分析;基于ANSYS有限元分析软件,以工程中某拱坝二维水平拱圈为例,进行了详细的拓扑优化分析,得到了较为满意的结果,这表明均匀化拓扑优化方法应用于拱坝水平拱圈的设计是可行的。

According to the arch dam features, with the object of the minimum volume, the form optimization design of arch dam is studied by using the homogenization method in topology optimization. Based on the finite element analysis software of ANSYS, 2 D horizontal ring topology optimization of some arch dam is accomplished. All the results are satisfied, which indicates that the topology optimization method is fit for the horizontal arch ring design.
