基于ANSYS Workbench软件,建立了圆形孔及轴向腰形孔的连续筛管模型,分析了不同割缝形式和过流面积比下连续筛管的屈曲性能。对连续筛管与单根连接筛管的下入效率和下入工艺过程进行了对比试验。研究结果表明,在4%、8%、12%等不同过流面积比条件下,轴向腰形孔型连续筛管的抗屈曲性能较好;连续筛管比单根连接筛管的下入效率提高了50%、下入阻力增加30%。 Based on the ANSYS Workbench software, a continuous sieve tube model with circular hole and axial waist hole was established. The buckling performance of continuous sieve tube with different kerf type and flow area ratio was analyzed. A comparative test was made on the efficiency of entering the continuous screen pipe and the single connecting screen pipe into the next process. The results show that the buckling resistance of the axial slotted continuous screen tube is better under different flow area ratios of 4%, 8% and 12% Increased efficiency by 50% and resistance by 30%.
