摘　　要：针对体积约束和结构柔顺度最小的结构拓扑优化问题,结合一种新的插值过滤技术,引入导重法,形成了一种考虑结构柔顺度要求和基于设计空间调整的结构拓扑优化方法.算例结果表明,该优化方法具有迭代次数少、收敛速度快和优化效率高等特点,并验证了其可行性和高效性.For the structure topological optimization problem with the objective function be- ing the compliance and volume constraints, combined with a new interpolation filter and guide-weight method, a new structural topology optimization method based on design space adjustments and compliance is proposed. The results show that the proposed method is of the advantage of less number of iterations, fast convergence speed and high efficiency, which also verify its feasibility and efficiency.
