液压球形防喷器胶心骨架的力学分析

Mechanical Analysis of the Reinforcing Segments of the Sealing Element of Hydraulic Spherical BOPs

通过液压球形防喷器胶心骨架力学模型的建立、载荷处理及有限元计算分析,确定了骨架结构的高应力后,为骨架结构的优化设计和等强度计算奠定了基础。

The author establishes a mechanical model for the steel reinforeing segments of the rabbet sealing element in a hydraulic spherical blowout preventer, determines the high stress region in the reinforcing segments by load analysis and finite element calculation. These lay a foundation for the optimization and the iso-strength calculation of the segments.
