摘　　要：在深海作业中,密封泄漏是深海装备发生故障的重要原因之一.可靠的密封可以很大程度上延长其单次水下作业时间和装备使用寿命,因此开展深海装备的密封技术研究具有重要的意义.文章以深海装备液压缸O形密封圈结构为研究对象,应用ABAQUS软件建立O形密封圈结构二维轴对称有限元模型,对深海不同水深压力情况下的不同压缩率和不同材料硬度的O形密封圈的密封性能进行有限元分析,探明深海高压环境对O形密封圈密封性能的影响规律,为深海高压环境下密封圈的优选以及优化设计等提供理论依据.In deep-sea operation,seal leakage is one of the important reasons for deep-sea equipment failure.Reliable sealing can greatly extend the time of single underwater operation and the service life of equipment,so it is of great significance to carry out the research on sealing technology of deep-sea equipment.In this paper,the O-ring structure of the hydraulic cylinder of deep-sea equipment is taken as the research object,and the two-dimensional axisymmetric finite element model of the O-ring structure is established by using ABAQUS software.The finite element analysis of the sealing performance of the O-ring with different compression ratio and different material hardness under different deep-sea water depth and pressure is carried out,and the influence of deep-sea high-pressure environment on the sealing performance of the O-ring is proved.It provides a theoretical basis for the optimization and optimization design of sealing rings under deep-sea high-pressure environment.
