中文摘要:
      为了提高井下防喷器旁通启闭短节密封性能分析的效率,基于Python语言和ABAQUS的GUI功能对ABAQUS进行二次开发,并提出一种参数化计算程序。所开发的程序能有效地减少利用ABAQUS研究井下防喷器旁通启闭短节密封时的重复工作,提高了工作效率。采用该程序分析不同载荷和配合锥角下旁通启闭短节阀芯-阀座的受力规律。结果表明:在阀芯-阀座的最大Mises应力不超过材料的屈服强度的情况下,随载荷的增大旁通启闭短节的密封性能变好,而随配合锥角的增大其密封性能变差。
英文摘要:
      In order to improve the analysis efficient of the sealing property of down hole blowout preventer(BOP) by pass open close nipple,ABAQUS was redeveloped based on Python language and ABAQUS GUI Toolkit,and a parametric calculation program was developed.The redeveloped program can efficiently deal with the repetitive work in studying the sealing property of down hole BOP by pass open close nipple by ABAQUS and improve the analysis efficiency.The program developed was applied to analyze the force acting on the valve core and valve seat of the by pass open close nipple under different loads and taper angles.The results show that when the maximum Mises stress of the valve core and valve seat does not exceed the yield strength of the material,the sealing performance of the bypass open close nipple is improved with the increase of load,while with the increase of the conic angle,the sealing performance is deteriorated.
