基于拓扑优化理论的桥梁结构找型

拓扑优化能够在给定边界条件下,给出结构合理的材料分布.基于变密度法,针对连续结构在不同约束条件下给出了悬臂结构、拱式结构、上承式悬带桥结构的拓扑优化结果及结构模型设计.结果表明,优化后的拱桥设计方案具有简洁性、有效性、实用性.

Pattern Finding of Bridge Structure based on Topology Optimization Theory

Topological optimization can give the material distribution with reasonable structure under given boundary conditions.Based on the variable density method,this paper presents the topology optimization results and structural model design of cantilever structure,arch structure and top bearing suspension bridge structure under different constraints.The results show that the design scheme of the optimized arch bridge is concise,effective and practical.
