摘　　要：以有限元软件为平台建立防喷器系统模型,模拟密封胶芯环空控制压力,进行密封胶芯的接触压力仿真计算。结果表明:胶芯密封面最大接触压力分布具备明显的非线性特征;胶芯最大位移(变形)和应力位于胶芯内圆柱面的中间环面部位。针对胶芯端面环空压力和液体推挤作用,可通过硫化防突铁芯工艺,有效抑制端面溢胶现象,延长胶芯使用寿命。Having the FEA software based to establish a blowout preventer model so as to simulate control pressure and to calculate contact pressure of the rubber core was proposed. The results show that the maximal pressure distribution in the rubber core＇ s sealing surface has obvious nonlinear characteristics ; and both stress and deformation concentrates on the core＇ s inner ring surface. The vulcanized iron rings in the rubber core can decrease the pushing deformation and the blowout at the end face so that the working life of the rubber core can be prolonged,
