| 摘 要： | 利用ABAQUS软件建立海底采油设备用O形密封圈轴对称模型,对其在不同压缩率、不同油压时的Von Mi-ses应力及密封面接触压力分布规律进行探讨,确定O形密封圈材料易失效位置;分析压缩率和油压对O形密封圈最大Von Mises应力、最大接触压力及最大接触压与油压压差的影响。结果表明:O形密封圈最大Von Mises应力、密封面最大接触压力随压缩率和油压的增加而增加,且O形密封圈在中低高压下的密封能力高于超高下的密封能力,为海底采油设备用O形密封圈的结构设计及选型提供相关参考。

| Abstract: | ABAQUS was utilized to establish the axisymmetric model of O-ring seals used for subsea production equipment.The distributions of the Von Mises stresses and the sealing surface contact stresses were discussed and the places of material failure were defined.The influence of compression ratios and oil pressures on the max Von Mises stresses,the max contact stresses as well as the differences of the max contact stresses and oil pressures were analyzed.The results show that the max Von Mises stresses and the ma... |
