摘要
以FH28-105型环形防喷器壳体为研究对象,结合其不同工况下的不同载荷特点,采用理论计算与有限元方法相结合,得到了壳体在静水试验压力和额定工作压力下的力学行为特性和应力情况,获得其危险部位,并对其进行强度设计评价.通过多 目标优化,以减重为 目标,同时兼顾壳体的强度以及校核标准,对环形防喷器壳体的结构尺寸进行优化.结果表明:初步设计的环形防喷器壳体强度满足要求,危险部位出现在壳体卡爪槽的圆弧倒角位置处以及壳体内腔下方的倒角过度处;环形防喷器最终优化方案满足强度要求,相比于原结构尺寸,质量和塑性应变的优化幅度最大,分别为19.7％、15.6％,其他目标均获得了不同程度的下降,实现了在保证壳体强度标准的条件下对壳体进行减重优化.
Abstract
The FH28-105 annular BOP shell was taken as the research object,combined with its different load characteristics under different working conditions,and the mechanical behavior characteristics and stress of the shell under hydrostatic test pressure and rated working pressure were obtained by combining theoretical calculation and finite element method,and its dangerous parts were obtained and the strength design was evaluated.Through multi-objective optimiza-tion,the structural dimensions of the annular BOP housing were optimized with the goal of weight reduction,taking into account the strength of the shell and the test standard.The results show that the strength of the annular BOP shell meets the requirements,and the dangerous parts appear at the circular chamfer position of the shell clamp groove and the excessive chamfer posi-tion under the shell cavity.The final optimization scheme of the annular BOP meets the strength requirements.Compared with the original structure,the optimization range of mass and plastic strain are the highest,with values of 19.7％and 15.6％,respectively,while other targets have been reduced to varying degrees,thus realizing the weight reduction optimization of the shell un-der the condition of ensuring the strength standard.
