摘　　要：以煤矿中使用的Y4-73型离心通风机为对象,基于有限元方法对不同叶型结构产生的通风机性能进行研究。首先对离心通风机及叶轮叶片进行简要概述,在此基础上利用SolidWorks和CFD软件构建了离心通风机的有限元模型,设计了板型、翼型和薄翼型三种叶片结构。通过对比研究发现,翼型结构在通风效率方面表现出了明显优势,在高流量状态下翼型结构全压系数也达到最大,所以建议使用翼型结构叶片。根据优化方案对离心通风机进行技术改造,对比发现技改后的通风机性能得到一定程度提升,在保障煤矿安全生产方面发挥了更重要的作用。Based on the finite element method,the performance of Y4-73 centrifugal fans used in coal mines was studied for fans with different blade structures.Firstly,a brief overview of the centrifugal fan and impeller blades is provided.Based on this,a finite element model of the centrifugal fan is constructed using SolidWorks and CFD software,and three blade structures,namely plate,airfoil,and thin airfoil,are designed.Through comparative research,it has been found that the airfoil structure exhibits significant advantages in ventilation efficiency,and the total pressure coefficient of the airfoil structure reaches its maximum under high flow conditions.Therefore,it is recommended to use airfoil structure blades.According to the optimization plan,the centrifugal ventilation fan was technically modified,and it was found through comparison that the performance of the modified ventilation fan has been improved to a certain extent,playing a more important role in ensuring coal mine safety production.
