| 中文摘要: |
| 本文在虚拟层合单元的基础上，为适应形状优化时边界变化的特点，构造了曲线分层的虚拟层合梁单元，这样，求解优化问题时仅把特定的层厚作为设计变量，无须改变原始数据结构，有限元网格只在优化初始生成一次即可，具有单元数少、设计变量少的优点，算例表明此法计算简便，结果可靠，具有良好的工程应用前景。 |
| 英文摘要: |
| The curvilinear virtual laminated beam element, which is based on a new type of virtual laminated element and can be used to the shape optimization that often causes the change of the boundary shape. In the new method, the specific layer thickness is taken as design variations, and it doesn't require changing the original data structure. Therefore it does not need to reform the finite element in the shape optimization. The calculated results show that this method is very simple, and have reliable results. We believe that this method can be applied in the future engineering design. |
