摘　　要：以矿用对旋式轴流通风机前后两级叶片为研究对象,应用响应面法(RSM)和三维流场分析对矿用对旋式轴流通风机前后两级叶片弯掠参数进行优化设计。首先定义矿用对旋式轴流通风机前后两级叶片弯掠参数,然后以矿用对旋式轴流通风机前后两级叶片的弯、掠角为设计变量,以通风机全压效率最大化为优化目标,建立前后两级叶片的弯、掠角与通风机全压效率的响应面模型,最后对各参数进行优化设计。结果表明,通风机全压效率提高了1.64%,通风机的气动性能得到进一步改善。The optimization design was studied using response surface methodology（RSM） and three-dimensional flow analysis for the mine contra-rotating axial fan two-stage blades.Firstly,the skew and sweep parameters of mine contrarotating axial fan two-stage blades were defined.Secondly,the response surface model that between the skew,sweep of two-stage blades and total-pressure efficiency of fan was established with the skew and sweep of two-stage blades as the variables,the total-pressure efficiency of fan as the object.Finally,the skew and sweep parameters of two-stage blades were optimized and the results show that the total-pressure efficiency of fan is increased by 1.64%.In addition,the aerodynamic performance of mine contra-rotating axial fan is improved.
