轴向压入式管接头过盈量的计算

【摘 要】为了达到轴向压入式管接头的连接强度和密封效果，计算管接头与管套的过盈量尤为重要。本文通过ansys软件对2英寸管径各厚度的管接头压接过程进行数值模拟，得出最佳过盈量，并得知随着管道厚度增加最佳过盈量随之降低。

abstract： in order to reach the connection strength and seal ability，it is important which magnitude of interference calculation of pipe fitting. the finite element method of ansys has been used in this paper to simulate the interference fit process of 2 inches of thickness pipe fitting，then we can obtain the magnitude of interference. as the pipeline thickness increases the magnitude of interference decreases. keywords： axial press-in-type pipe fitting；seal ability； magnitude of interference；the finite element；thickness 1.引言
