摘要
根据乌东德水电站左岸导流隧洞进水口渐变段的结构形式,设计了一种大型双曲面衬砌钢衬。利用有限元软件ANSYS对设计方案进行了静力学分析,结果表明初始方案的结构应力偏大,且重量过大,有必要对方案进行改进。基于WORKBENCH的拓扑优化结果,提出了一种改进方案,并对改进方案进行了验证。改进方案与初设设计方案相比减轻了47.0%的重量,节约了成本,且刚度和强度均满足施工要求。可为类似工程提供有效借鉴。
According to the structural form of the transition of the water intake area in the left diversion tunnel of Wudongde hydropower station,a large hyperbolic steel liner was designed. The static analysis of the design scheme was conducted using the finite element software ANSYS. The results showed that the structural stress of the initial design scheme of mold is high and the weight is large, so the design scheme needs to be improved. According to the topological optimization results based on WORKBENCH,an improved design scheme was proposed and verified,which can decrease the weight of mold by 47.0% compared with the original scheme. Meanwhile the cost was saved and the stiffness and strength of the mold satisfied the construction requirement. The research results can provide reference for the similar engineering projects.
