摘　　要：文章将FLUENT三维仿真和动网格技术引入到了饲料粉碎机的结构优化设计中,设计出了一款效率更高的饲料粉碎机结构,为了验证该结构的高效性和可靠性,采用数值仿真模拟的形式对新饲料粉碎机的内部流场结构进行仿真计算,建立了FLUENT饲料粉碎机粉碎室流场和饲料粉碎机运动动网格的数学模型,并设计了UDF算法程序。通过计算得到了饲料粉碎机内部的速度场云图和不同入口速度下的流场中的最大速度值,将计算结果和初始结构进行对比发现,改进后的结构获得的风速更大,提高了饲料粉碎机的粉碎效率。This article put Fluent 3D simulation and dynamic grid technology into the feed mill struc-ture optimization design, designed a kind of efficient feed mill structure, in order to validate the effi-ciency and reliability of the structure, this article adopts the numerical simulation for the new feedmill, in the form of internal flow field structure of the simulation calculation, feed mill crushing cham-ber is established Fluent flow field and feed mill dynamic mathematical model of the grid, and designsthe UDF algorithm procedures. By calculating the velocity field of the feed mill nephogram and themaximum velocity of flow field under different inlet velocity value and the calculated results were com-pared with the initial structure, it found that the improved structure of wind speed, improve the feedmill grinding efficiency.
