摘要
悬垂下放法(Pendulous Installation Method,简称PIM)是针对超深水环境和较大重量管汇的安装专门设计的一种快捷、简便的安装方法,更适用于新一代水下生产系统.本文基于多体动力学软件ADAMS对功能舱的下放过程进行仿真,将功能舱简化为球体加圆柱体的组合体形式,以多段小圆柱体加轴套力的形式近似模拟缆索,参考Morison公式进行绕流阻力的计算,建立了悬垂下放多刚体动力学仿真模型.通过与其他参考文献结果对比验证了模型的有效性.讨论了流体速度、功能舱重力和缆索长度等对下放过程的影响.本文研究内容可对新一代水下生产系统功能舱的工程应用提供理论指导.
The pendulous installation method(PIM)is a quick and convenient installation method specially designed for the installation of ultra-deep water and large weight manifolds.This is more suitable for the new generation underwater production systems.This article simulates the pendulous process of the function module with ADAMS software.The function module is simplified as a combination of a sphere and a cylinder.The cable model is approximately simulated in the form of a multi-segment small cylinder plus bushing force.The Morison formula is used to calculate the flow resistance.A multi-rigid-body dynamic simulation model by pendulous installation method was established.The validity of the model is verified by comparing the simulation results with other references.The effect of fluid velocity,gravity of the function module and cable length on the pendulous process is discussed.The research content of this paper can provide theoretical guidance for the engineering application of the function module of new generation underwater production systems.
