基于ANSYS Workbench的复合式发酵塔装置重要零部件有限元分析
|
摘要
以复合式发酵(好氧厌氧结合)塔装置为研究对象,通过Solidworks建立复合式发酵塔三维实体模型,并对复合式发酵塔进行了简化。利用ANSYS Workbench有限元分析软件识别结合面特征,建立复合式发酵塔装置重要零部件的有限元模型。通过理论计算与有限元分析的结合,分析得出螺旋杆轴受力较小,叶片受力大,叶片两端受力最大,隔板右上端面厚度太小以至于承受不住物料的压力。
Taking the composite fermentation(aerobic anaerobic combined) tower device as the research object, the solid threedimensional solid model of the composite fermentation tower was established by Solidworks, and the composite fermentation tower was simplified. The ANSYS Workbench finite element analysis software was used to identify the characteristics of the joint surface, and the finite element model of the important parts of the composite fermentation tower was established.Through the combination of theoretical calculation and finite element analysis, it is found that the screw shaft has less force,the blade is subjected to large force, and the force at both ends of the blade is the largest. The thickness of the upper right end of the diaphragm is too small to withstand the pressure of the material.
