基于ANSYS的双卡套接头螺纹密封性有限元分析
Finite Element Analysis of Thread Tightness of Double-Ferrule Joint Based on ANSYS
摘要
Abstract
Card sleeve joints are widely used in the connection of hydraulic and pneumatic equipment such as oil and gas pipelines,and its connection reliability has an important impact on the safety of oil and gas pipelines.However,there is no report on the influence of external working conditions on the stress characteristics of the thread of card sleeve joints in oilfield ground pipelines.A three-dimensional model of the double card sleeve joint was established using SolidWorks software;The maximum equivalent stress(Von Mises stress)of the sleeve joint was numerically analyzed using ANSYS finite element software.The results indicate that within the yield limit,the greater the axial force,the better the sealing performance of the sleeve joint,while the internal pressure has little effect on the sealing of the pipe joint,and the risk of thread sticking due to excessive stress can be ignored;The influence of thread parameters on sealing performance is significant;The optimal pitch and number of threads for a sleeve joint with an outer diameter of 12 mm and an inner diameter of 9 mm are 1.5 mm and 7,respectively.The research results can provide theoretical basis and reference for the optimization of structural performance and scientific operation in the assembly process of card sleeve joints,which has important engineering significance.关键词
