井喷冲击作用下环形防喷器动力响应

Dynamic response of annular blowout preventer under blowout impact

环形防喷器在井喷作用下抗冲击能力不容忽视.利用ABAQUS大型有限元分析软件对某型环形防喷器进行动态分析,进行结构校核并确定出其受力薄弱部位,得出了应力及变形的动态响应,为防喷器的使用及检验提供了一定的参考依据.

The impact resistance of annular blowout preventer under blowout action cannot be ignored. Using ABAQUS large finite element analysis software, the dynamic analysis of a certain type of annular blowout preventer was carried out, the structure was checked and the weak part of the force was determined, and the dynamic response of stress and deformation was obtained, which provided a certain reference basis for the use and inspection of the blowout preventer.
