    彎曲載荷下特殊螺紋接頭密封性能的有限元分析

    Finite Element Analysis of Sealability of Premium Connections Subjected to Bending Load

    • 摘要: 借助Abaqus軟件建立了特殊螺紋接頭彎曲性能分析有限元模型,并對(duì)某個(gè)規(guī)格特殊螺紋接頭進(jìn)行了純彎曲的有限元分析。結(jié)果表明:隨著彎矩的增加,拉伸面接觸應(yīng)力下降,接觸長(zhǎng)度減小,密封性能下降;而壓縮面接觸應(yīng)力上升,接觸長(zhǎng)度增加,密封性能提高。這些結(jié)果說(shuō)明提高特殊螺紋接頭的彎曲性能需要同時(shí)提高接頭的拉伸與壓縮性能。

       

      Abstract: The finite element analysis(FEA)methodology for premium connections subjected to bending load is established with the software of Abaqus, and then used for pure bending property analysis of premium connections with a certain size. The results reveals that along with the increasing of the bending moment, the contact stress, contact length and sealability decrease in the tensile side, whereas all of these values increase in the compression side, which implies that for improving the bending property of the premium connection both the tensile property and compression property thereof should be enhanced, too.
