摘要
对水下用FHZ48-70型环形防喷器承压件——壳体和顶盖进行了有限元分析。壳体和顶盖采用爪块式连接,该处结构对总体安全性和结构合理性有着重要影响,对连接齿的个数、角度和高度进行了优化设计。经过对计算结果的应力线性化处理,得出了该防喷器设计符合API 16A规范的结论,并通过了厂内试验验证。
Through Finite element analysis of FHZ48-70 annular pressure-containing parts—body and head for subsea blowout preventer,it offers theoretical support.Body and head are joined by craw,optimized design was completed for number,angle and height of teeth.It was affected to the security and rationality of BOP.By stress linearization,the result shows that the configuration met the API specification,the BOP tests were completed in factory.
