摘　　要：以水动力节能装置经典伴流补偿导管为研究对象,提出利用响应面模型综合评价导管设计参数并进行优化.以导管结构特征尺寸为设计参数,建立节能导管的参数化模型.以KP505螺旋桨和节能导管耦合的水动力计算结果为响应参数,生成响应面模型.将螺旋桨效率提升比作为优化目标,将导管结构特征尺寸阈值作为约束条件,基于二阶响应面模型对导管进行结构优化设计,并对优化结果进行仿真验证,证明响应面模型的可靠性.结果表明,优化后桨-管系统的效率提升比增大了37.82%,说明利用构建的响应面模型对节能导管进行优化合理有效,可为其他类型的节能导管设计提供参考.Taking a hydrodynamic energy-saving device-classical wake equalizing duct as the research object,a response surface model is proposed for comprehensive evaluation and optimization of the duct design parameters.Taking the feature dimensions of the duct structure as the design parameters,the parametric model of the energy-saving duct is established.The coupling hydrodynamic calculation results of KP505 propeller and energy-saving duct are taken as the response parameters to generate the response surface model.The propeller efficiency improvement ratio is taken as the optimization objective,and the feature dimension threshold of the duct structure is taken as the constraint condition.Based on the second-order response surface model,the structural optimization design of the duct is carried out,and the optimization results are simulated and verified to prove the reliability of the response surface model.The results show that the efficiency improvement ratio of the optimized propeller-duct system increases by 37.82%.Therefore,using the constructed response surface model to optimize the energy-saving duct is reasonable and effective.It can provide reference for other types of energy-saving duct design.
