- 摘要:
- FPSO关键管路系统的安全直接关系到整体FPSO的安全，管道系统在运行过程中产生的振动问题往往也会导致直接的经济损失，因此展开对FPSO关键管路系统的减振控制研究至关重要。运用Workbench软件对管路系统进行模态分析，通过分析管道固有频率变化规律来避开共振区，防止机械共振，为管路系统在设计阶段提供思路；针对要求抗振动的管道系统，建立合适的管道力学模型进行理论推导，得出相应的管道系统安全跨距的计算公式，用数值模型来验证公式的正确性并进行相应的支撑布置来防止管道振幅过大。
The safety of FPSO key pipeline system is directly related to the safety of the whole FPSO. The vibration problem of pipeline system in the process of operation will often lead to direct economic losses. Therefore, it is very important to carry out the vibration control research of pipeline system. Using the Workbench modal analysis was carried out on the piping system. By studying the variation law of the natural frequency of the pipeline, the resonance area is avoided and the mechanical resonance is prevented, which provides ideas for the pipeline system in the design stage; For the pipeline system that requires anti-vibration, establish a suitable pipeline mechanics model for theoretical derivation, and obtain the corresponding calculation formula for the safety span of the pipeline system, and the theoretical span of the pipeline is calculated to determine the support layout of the pipeline, so as to prevent the excessive amplitude of the pipeline.
