摘　　要：针对目前广泛使用的SL225型水龙头提环存在的结构性安全问题,利用ANSYS软件对其进行了有限元分析,分别得出了3种载荷形式下的整体应力与变形规律。结果表明,载荷为1 500 kN时,强度远大于要求,变形小于0.670 mm;载荷为2 250 kN时,轴孔处应力略高,基本能满足强度要求,变形小于1.104 mm;在3 500 kN载荷下,多处应力过高,强度不满足要求,整个变形小于1.607 mm。Aiming at structural safety problem on SL225 swivel bail widely used in oil field at present, the finite element analyses were made under the three load conditions. The result of static analysis showed that the strength exceeded the requirement at 1 500 kN load and the deformation was within 0. 670 mm. When the load capacity is 2 250 kN the stress around shaft hole was higher, which basically met the requirement as the deformation was within 1. 104 mm, while at 3 500 kN load higher stress appeared at most locations, which obviously dissatisfied the requirement of engineering although the deformation within 1.607 mm.
