摘　　要：网架结构的拓扑优化设计对结构性能及其耗材量有着至关重要的影响。利用OptiStruct软件,分别对3种跨度和3种约束工况下的铝合金网格进行拓扑优化,并根据拓扑优化结果进行结构设计,计算拓扑优化后的铝合金网架耗材量。对比分析了不同跨度及约束条件下拓扑优化后铝合金网架与钢网架的用材量。与传统钢网架相比,按拓扑优化设计方法得到的铝合金网架,其耗材量会大大降低。The topological optimization of grid structure is of great significance for the performance and material consumption. Based on OptiStruct software,topology optimization is carried out for aluminum alloy grids with three kinds of span and three kinds of constraint conditions. The corresponding design is proceeded according to the topology optimization results to obtain the aluminum alloy grid frame consumption. The material consumption of aluminum alloy grid and steel grid after topological optimization is analyzed and compared in different spans and different working conditions. The results show that the consumption of optimized aluminum alloy grid is much less than that of traditional steel grid.
