本文提出了一种基于移动可变形构件（MMC）的曲面骨架（中心线）显式拓扑优化方法。这是通过构造拓扑描述函数（TDF）来实现的，该函数以优雅的方式明确地描述了具有弯曲骨架的结构部件的几何形状。所提出的方法具有非常灵活的几何建模能力，并代表了现有的MMC为基础的方法的几何建模能力的实质性改进。数值算例验证了该方法的有效性。(C)2016爱思唯尔B.V.保留所有权利。
In the present paper, an explicit topology optimization approach based on moving morphable components (MMC) with curved skeletons (central lines) is proposed. This is achieved by constructing the topology description function (TDF) which describes the geometry of a structural component with curved skeleton explicitly in an elegant way. The proposed method has very flexible geometry modeling capability and represents a substantial improvement of the geometry modeling capability of existing MMC based approaches. Numerical examples demonstrate the effectiveness of the proposed approach. (C) 2016 Elsevier B.V. All rights reserved.
