| 摘 要： | 对抢修在役长输管线所需的一种带压封堵器建立了三维模型,利用ANSYS Workbench软件,分析了封堵器在实施封堵时的受力分布。在6.4MPa的实际操作工况下,封堵器所承受的最大等效应力出现在支撑架和轴套焊接处,其大小为212MPa,选取钢材材料为Q345及屈服强度大于Q345的材料,安全系数取1.5,许用应力为230MPa,能够满足强度要求,只留有较少的余量。针对封堵器结构受力不均匀的情况,对其进行优化设计。提出的4种优化方案中支撑板开孔可以在最大应力增长不大的情况下明显减少机构质量。

| Abstract: | The plug's 3D model was established to analyze stress distribution based on ANSYS Workbench software.The result shows that plug's maximum stress can be 212MPa at the welding point between support frame and shaft sleeve under a 6.4MPa operation pressure;and selecting steel materials with yield strength to be Q345 and above and with a 1.5 safety factor and a 230MPa allowable stress can meet the strength requirements along with a small margin.Considering unevenness of the plug's structure,4 optimal schemes were proposed;and optimizing support frame's opening can reduce plug weight without increasing maximum stress growth. |
