基于Workbench的浓密机中心轴吊点位置的优化

Optimization of hanging point position of thickener center shaft based on Workbench

针对中心传动式浓密机的中心轴整体变形、等效应变和最大应力较大的情况,介绍了一种基于Workbench优化技术进行中心轴吊点位置选取的方法.对中心轴进行受力分析,定义优化变量,将整体变形、等效应变和最大应力作为目标函数,基于Workbench的不断迭代计算得出几种优化方案和目标函数曲线图,经比较选出合适的方案,并对选取的方案做了进一步的验证.结果表明,优化后的整体变形、等效应变和最大应力有了显著的改善.

A method for the selection of the hanging point position of the center shaft based on the Workbench optimization technique is introduced on the matter of the center shaft of the central drive thickener, such as the total deformation,the equivalent strain and the equivalent stress maximum. Force analyses are conducted on the center shaft and the optimization variables are defined. Put the total deformation, the equivalent strain and the equivalent stress maximum as the output variables. Several optimization schemes and the diagrams of the hinge point position with the optimization goal are obtained through the continuous iterative calculation of Workbench. The optimal scheme is chosen in accordance with the chart. Finally, further validation of the selected scheme is made. The results show that there is a big improvement in the optimization of the total deformation, the equivalent strain and the equivalent stress maximum.
