袋式除尘器脉冲喷吹方形气包变形的分析

Deformation Analysis of the Fabric Filter Impulse Blowing Square Air Tank

采用ANSYS软件对所设计的方形气包建立有限元分析模型,并针对上表面变形量过大的情况,提出了在相同位置分别焊接10 mm×100 mm的扁钢或直径为15 mm的圆钢的措施。分析表明,计算流程实现了完全的参数化设计,只需改变气包的结构尺寸,就能自动地建立气包变形分析模型,从而达到满意的控制效果。

In this paper, the FEM （ finite element model） of the square air tank is constructed with the ANSYS software. Aimed at the oversize deformation of the upper surface, the authors propose to weld the 10 mm × 100 mm steel tubes or the 15mm steel tubes in the same position. The analysis shows that the total parameter design can be realized with the FEM of the square air tank built automatically if the structure sizes are given. This method has offered an efficient tool for the design.
