Structural topological optimization based on the moving asymptotes approximation and guide-weight method

针对结构柔顺度最小和体积约束的结构拓扑优化问题,引入了一种新的插值过滤函数和移动渐近近似函数。基于导重法和设计空间调整技术,形成了一种考虑结构柔顺度要求的结构拓扑优化方法。算例验证结果表明,该优化方法迭代次数少,收敛速度快,优化效率高。

For the structural topology optimization problem with the obj ective function being the structural compliance and its volume constraint,a new interpolation filtering function and a moving asymptotes approximation are introduced.Based on the guide-weight method and the design space adj ustment technology,a new structural topology optimization method for minimizing the structural compliance is proposed .The results show that the proposed method is of a less number of iterations and a faster convergence speed than the convention-al method.
