[求助] 求帮助翻译下这段英文摘要,本人新手想看一下正确的翻译和自己翻译的差异

This study presents the integrated layout optimization of multi-component systems using a fixed mesh.The optimization formulation is established under the framework of the extended finite element method(XFEM). The level set method is used to represent components and is combined with the XFEM to describe material discontinuities across elements. Sensitivity analysis is proposed with respect to geometric variables of components and pseudo-densities of the basic structure. An analytical shape sensitivity analysis method with respect to positions and shapes of components is developed. Both solid and void components are considered to show the efficiency and accuracy of the proposed shape sensitivity analysis method. Furthermore, a revised finite circle method that adapts shape changes of elliptical components is proposed for the definition of non-overlapping constraints. Finally, numerical examples of maximizing the structural stiffness are tested to demonstrate the proposed method.

这项研究展示了使用固定网格得出的多组元系统的集成布局最优解。最优化公式建立在拓展有限元法的框架之下。采用水平集方法来代表组元并结合拓展有限元法来描绘材料在单元上的不连续性。基于组元的几何变量及基础结构的伪密度提出了敏感度分析法。基于组元的位置和形状开发了一种分析形状敏感度的分析方法。固态及空组元都被考虑在内以体现文中提出的形状敏感度分析方法的高效性及准确性。并且,基于非重叠约束条件的定义提出了一种能适应椭圆组元形状改变的改进有限循环方法。最后,通过大量最大化结构刚度实例的测试来证明提出的这种方法。
