环模燃料制粒机结构设计及仿真研究

Structure Design and Simulation Research on Ring Die Fuel Pellet Machine

在分析我国环模燃料制粒机设计和运行中存在问题的基础上,对制粒机的关键部件进行优化。在拟定环模和压辊相关设计参数后,根据疲劳破坏理论确定合理的压辊数目。应用Pro/E软件对制粒机进行三维实体建模,通过专用接口软件Mech/Pro将模型导入ADAMS中进行动力学仿真分析。结果表明:当压辊数目为4个时,环模上作用的应力幅最小,制粒机的能耗比最低。说明通过合理设置压辊数目,可以有效提高环模使用寿命和设备生产效率。

The problems existing in the design and operation of ring die fuel pellet machine were anslyzed, and the key parts optimized. The reasonable number of roller was determined on the theory of fatigue damage after drawing up the related design parameters of ring die and the roller. A three-dimensional model of the link mold pellet pelletizer was established using Pro/E soft ware, and transferred into ADAMS software through Mech/Pro which dedicated interface software, then used ADAMS to make a dynamics simulation. The result showed that the stress amplitude impact on the ring die and the Energy consumption per unit output was smallest when roller number was four. Ring die service life and equipment production efficiency can be improved effectively through setting up reasonable roller number.
