合理分析管系的水锤效应，对管系的安全性、经济性都有着十分重要的意义。目前对水锤效应的研究往往只考虑流体与管道之间的作用情况，忽略了管系中管道与支架的整体性。为更加准确的计算管系水锤效应发生界面的水锤压力大小，以某深水通用性FPSO管道支架参数为基础，设计了一种易于简化计算的管系模型，通过对比分析仅考虑管道内流体、考虑管道内流体与管道耦合以及管道内流体与管路支架整体系统双向流固耦合时，水锤效应的情况。结果表明，仅考虑管道内流体、考虑管道内流体与管道耦合时，对水锤压力大小影响不大。当管道内流体与管路支架整体系统双向流固耦合时，计算结果有较为明显的降低（在计算工况下降低约6.06%），其原因在于管道支架在水锤效应发生时，产生了一定的变形（在计算工况下最大位移为0.0472 m）。
Reasonable analysis of water hammer effect of pipeline system is of great significance to the safety and economy of pipeline system. At present, the study of water hammer effect often only considers the interaction between fluid and pipeline, ignoring the integrity of pipeline and support in the pipeline system. In order to more accurately calculate the water hammer pressure at the interface where the water hammer effect occurs in the pipeline system, a pipeline model that is easy to simplify the calculation is designed based on the parameters of a deep-water universal FPSO pipeline support. Through comparative analysis, the water hammer effect is considered when only the fluid in the pipeline is considered, the fluid and pipeline coupling in the pipeline are considered, and the two-way fluid solid coupling between the fluid in the pipeline and the overall system of the pipeline support is considered. The results show that only considering the fluid in the pipeline and considering the coupling between the fluid in the pipeline and the pipeline has little influence on the water hammer pressure. When the fluid in the pipeline and the overall system of the pipeline support are coupled in a two-way fluid solid way, the calculation results have a significant reduction (about 6.06% in the calculation condition), because the pipeline support has a certain deformation when the water hammer effect occurs (the maximum displacement is 0.0472 m in the calculation condition).
