本文描述了对万能防喷器的应力测定。在解决高水压下应变,测试技术的基础上,分析了万能防喷器内外壁的应力分布,比较了两种结构型式万能防喷器的力学强度,阐明了材质参数和操作工艺对万能防喷器力学强度的影响。 This article describes the stress measurement of a universal blowout preventer. On the basis of solving the strain and test technology under high water pressure, the stress distribution on the inner and outer walls of the universal BOP is analyzed. The mechanical strength of the two types of universal BOP is compared. The effects of the material parameters and operation process on the universal anti- Impact of the mechanical strength of the jet.
