摘　　要：对于封隔器等水下设备,胶筒的密封性能极为重要,而胶筒的截面形状是影响胶筒密封性能的重要因素之一。在胶筒受到过大的轴向行程时,会出现肩突,从而导致密封失效。为防止出现肩突,文中定义一个新的参数,防肩突变量。在利用有限元软件进行压缩胶筒的仿真过程中,当防肩突变量不小于0时,则胶筒不会发生肩突。文中提出的防肩突变量对橡胶和类似密封件的有限元仿真研究有重要的理论意义。The sealing performance of the rubber packer is of vital importance for subsea retractable connector such as packer,and the cross-sectional shape of the rubber packer is one of the most important factors affecting the sealing performance of the rubber packer.Shoulder extrusion occurs when the rubber packer is subjected to excessive axial distance,resulting in sealing failure.A new parameter called anti-shoulder extrusion variable is defined to prevent shoulder extrusion.When the anti-shoulder extrusion variable exceeds or equals zero,shoulder extrusion will not occur on rubber packer in the simulation process of the rubber packer compression using finite element software.The proposed anti-shoulder extrusion variable has important theoretical significance for the finite element simulation of rubber seals and similar seals.
