基于Workbench的浓密机中心轴的优化与分析
|
摘要
为防止因浓密机中心轴所受扭矩过大造成压靶事故现象的发生,优化设计浓密机中心轴与靶架间的连接方式,并对两中心轴建立扭矩模型,利用ANSYS Workbench对其在极限扭矩下进行瞬态动力学仿真分析,比较应力应变情况。结果表明,优化后的中心轴不仅安装方便,易于维修,能满足强度、刚度要求,而且所受的极限扭矩大大降低,变形量也减小很多。
In order to prevent too large torque of thickener center shaft, which will cause accident of pressure target, the connection mode between the central axis of the thickener and the target frame is optimized, the torque model of the two central axises is established, ANSYS Workbench is used to analyze the transient dynamic simulation under the limit torque, and the stress and strain conditions are compared. Results show that the optimized central axis has the advantages of convenient installation and easy maintenance, meeting the requirements of strength and rigidity, and the ultimate torque is greatly reduced, the deformation is also reduced a lot.
