为了解决拓扑优化分析计算量大和材料分布等问题,提出一种不影响算法收敛性的设计空间调整手段.针对体积约束和柔顺度最小的结构拓扑优化问题,采用变体积约束限的方法控制柔顺度变化的步长,然后,根据优化准则法,提出一种新的考虑柔顺度要求的结构拓扑优化方法.研究结果表明:该方法具有较高的求解效率,同时能够获得较好0～1分布特征的优化拓扑.%Based on the fact that the structural domain need be divided into some finite element meshes when structural topology optimization is made, and some optimization problems may need a large finite element mesh, a new structural topology optimization method was proposed. The minimum compliance topology optimization of continuum structures was dealt with volume constraint. The moving of compliance and process of iteration were controlled by the varying volume constraint, an optimality criteria was incorporated, and a new structural topology optimization method subject to compliance was proposed. The results show that the proposed method has higher efficiency, and is robust and practicable, making the optimum structure obtained with 0-1 distribution material property.
