ANSYS环模制粒机试验样机的三维设计与性能分析
摘要制粒机是饲料机械的四大主机之一，在饲料工业中占有很重要的地位。目前，国内饲料机械企业虽然在制粒机的设计、制造领域取得了很大进步，产品的外观、性能指标不断提高，但是与国外同类型设备相比较，仍然存在结构不合理，生产效率偏低、能耗偏高等缺陷，这极大地制约了产品的国际竞争力。62936
本课题所设计的环模制粒机主要用于饲料生产，主要对环模制粒机的喂料系统、调质系统、制粒系统，传动系统四个主要部分进行了设计；并应用了PROE软件进行了三维实体建模；应用ANSYS软件对关键部件进行性能分析与强度校核，得到了零件受载情况下的应力应变图；最后绘制了双螺杆挤压膨化机的二维工程图。
本文研究成果对环模制粒机产品的研发、优化有一定的借鉴意义。

Title Rotating Ring Die Pellet Mill Design And Performance Analysis
Abstract Rotating ring die pellet mill is the key device of producing pellet feed，to a large extent determines the production of feed processing．And now Rotating ring die pellet mill is widely used in animal husbandry，poultry industry，fisheries，and SO on．At present，the pelleting mechanism study of the rotating ring die pellet mill is few in china．Comparing the pellet mill with the same type of foreign，there are still many defects，such as irrational structure，low productivity，high energy consumption，which significantly restricted the international competitiveness of our products．
The rotating ring die pellet mill in this paper is used for feed production. The article contains the design process of four main part of the machine--the transmission system, the feeding system，the quenching device and the Pelleting system. Besides a dimensional solid model made by Pro Engineer software is presented. Then conduct performance analysis and strength check of key component using finite element software. Finally, draw two-dimensional drawings of the twin-screw extruder.
This article has been designed on the basis of innovation. It can be a reference to product research and optimize of the Rotating ring die pellet mill.
Keywords Rotating ring die pellet mill Dimensional solid modeling Finite Element Analysis
