摘　　要：应用有限元分析软件ANSYS对比无槽管板孔胀接接头性能与双槽管板孔接头性能的差异,讨论了不同开槽参数对双槽管板孔接头连接强度、密封性能的影响,并获得了最优的开槽参数。结果表明,在相同条件下,双槽管板孔接头连接强度、密封性能优于无槽管板孔接头。影响接头连接强度、密封强度的主要因素是胀槽宽度,胀槽深度、槽间距次之,胀槽位置影响较小。By use of finite element software ANSYS, the performance of expanded joints without groove and with two grooves was compared, and effect of structure parameter was investigated. Results show that the capacity and tightness of the joint with two grooves are better than the joint without groove under the same condition. The most important factor affecting the performance of joint is the groove width. The effect of groove depth and groove spacing is secondary, and groove location has a smaller effect.
