摘要
深水油气的开采已日益成为各国关注的重点,对于深水闸板阀,由于其在无潜条件下由液压执行机构操作,可视化位置指示器是其重要组成部分,国内对于该项技术的研究还处于空白阶段。设计的闸板阀可视化位置指示器可以在1500m水深条件下实现闸板位置实时指示,可视性好,可靠性高,便于水上操作人员进行相应的控制。通过ADAMS和Abaqus对其进行了运动学、动力学仿真和强度分析,对关键结构进行了强度分析验证其满足强度要求,并通过运动学仿真验证了机构在运动中无阻滞现象,进一步验证设计的合理性,为其传动机构的设计及样机的研制提供了理论依据。
The exploitation of deep-water oil and gas has increasingly become the focus of concern in all countries.For deepwater gate valves,due to its operation by the hydraulic actuator in the condition of no diving people,the visual position indicator is one of the most important parts,and research on this technology in our country is still blank.The visual position indicator for the gate valve can be in 1500m depth conditions to realize real-time position indication which has good visibility and high reliability,so that operation-persons on the surface can carry on the corresponding control.Based on the kinematics,simulation and strength analysis with ADAMS and A baqus,strength analysis for the key structures has been made to verify to meet the strength requirement,and no blocking phenomenon has been also verified in the operation process through the kinematics simulation,which further proves the rationality of the design and provides a theoretical basis for the hydraulic system design and the prototype development.
