摘　　要：针对石油钻井机械泥浆泵关键部件空气包在钻探过程中能否满足5000 PSI压力工况下的工作状态问题,建立空气包强度计算模型,基于我国压力容器标准对空气包壳体的强度进行校核,最后通过Solideworks和ANSYS软件对排出空气包的承载能力进行有限元分析。通过分析,得到排出空气包的最大等效应力、最大主应力、最小主应力及第二主应力,并得出各个应力最大值所在的位置,分析结果表明,排出空气包在5000 PSI(34.5MPa)的工作压力下是安全可靠的。Aiming at problems of whether the discharge dampener which is the key element of mud pump could work well un-der the pressure of 5000PSI, the strength calculating model is built in this article. Based on Chinese pressure vessel standard,strength of the shell body of dampener is checked. Finally, the loading capability of dampener is analyzed by using the SOLID-WORKS and ANSYS software. Through the analysis, the maximum equivalent stress, maximum main stress, minimum mainstress and the second main stress are obtained, and positions of the maximum stresses are also obtained. The analysis resultshows that the spherical shell of discharge pulsation dampener is safe under pressure of 5000PSI （34. 5MPa）.
