摘　　要：针对因轧制工艺排布不合理而降低叶片表面质量的问题,采用单因素实验方法分析不同压下率ε、摩擦因数μ和轧制速度v等工艺参数对叶片表面性能的影响规律。采用正交实验方法建立叶片的表面粗糙度、硬度以及残余应力预测模型,并基于Design-Expert检验法验证预测模型的显著性。以表面粗糙度最小、硬度和残余应力最大为多目标函数,采用差分进化算法对不同轧制工艺进行了优化,获得叶片轧制工艺优化参数为ε=13%、μ=0.04、v=6 mm·s^(-1),对应的硬度值为329.8 HV、表面粗糙度为0.317μm、残余应力为-738.5 MPa,该研究结果为叶片的轧制加工提供了数据支撑。For the problem of reducing the surface quality of blade due to unreasonable rolling process arrangement,the influences of different process parameters such as reduction rate ε,friction coefficientμand rolling speed v on the surface performance of blade were analyzed by single factor experiment method.Then,the surface roughness,hardness and residual stress prediction model of blade were established by orthogonal experiment method,and the significance of the prediction model was verified based on Design-Expert test method.Furthermore,taking minimum surface roughness,maximum hardness and maximum residual stress as the multi-objective function,the different rolling processes were optimized by differential evolution algorithm,and the optimization parameters of rolling process for blade were obtained as ε=13%,μ=0.04,v=6 mm·s^(-1).The corresponding hardness was 329.8 HV,the surface roughness was 0.317μm,and the residual stress was-738.5 MPa.Thus,the research results provide data support for the rolling processing of blade.
