摘　　要：针对割缝筛管不同缝槽排列形式会影响筛管抗挤强度的问题,考虑了平行、交错和螺旋3种不同的布缝形式,并以有限单元法为基础,同时建立割缝筛管的力学模型,分析出割缝筛管在3种不同布缝形式下的抗挤强度。计算结果表明,平行和交错布缝形式对割缝筛管抗挤压强度的影响基本相同,而螺旋布缝对割缝筛管抗挤压强度影响比前两种更大。研究结果可为合理地选择割缝筛管的参数,延长其使用寿命提供一定的理论依据。Considering the effect of slot arrangement on the collapse strength of slotted liner, the parallel, stagger and spiral three different slot arrangements have been studied?Based on the finite element method, the me?chanical model of the slotted liner is established to analyze the collapse strength of the slotted liner in three different slot arrangements?The results show that the effects of parallel and staggered slot arrangements on the collapsing strength is basically the same, while the spiral slot arrangement results in a greater collapsing strength than the pre?vious two arrangements?The results could provide theoretical basis for parameters selection for slotted liner to im?prove its service life.
