摘　　要：为解决对撞式流化床超细气流粉碎机分级叶轮力学性能分析的难题,提出了一种有限元数值模拟分析方法,并针对一直径为220mm,转速为7000r.min-1的分级叶轮,详细介绍了有限元分析过程,给出了分级叶轮叶片上的综合应力分布云图及沿叶轮长度方向的应力分布曲线。该分析方法可以在同类结构的应力分析中推广应用。Stress-distributing of the grading wheel in an opposed fluidized-bed jet mill by traditional method is difficult and complex. The paper presents a method based on finite element analysis to solve this problem. Detail analysis process and results are introduced using a grading wheel with diameter 220 mm and rotational speed 7000 r·min-1 as an example. The contour map and curve of stress-distributing in a blade of the grading wheel are obtained. The method can be used to the similar products.
