摘要
为了研究浮式生产储卸油装置软刚臂系泊系统在服役海况下的多体动力学行为,本文将软刚臂系泊系统的铰结构进行拆分,结合现场原型监测信息,开展了适用于现场应用的软刚臂系泊系统的三维多体动力学模拟研究。利用现场监测冗余信息,验证了多体动力学模拟方法对在役软刚臂系泊系统各铰和单体运动状态计算的正确性。同时,相对于传统的软刚臂结构的二维力学模型而言,本文所提出的三维多体动力学模型全面地考虑了船体和系泊结构运动的影响,系泊回复力具有明显的波频效应,可更加全面地表征软刚臂系泊系统在服役状态下的结构运动姿态和受力等实时工作状态。
To study the multibody dynamic behavior of the soft yoke mooring system(SYMS)of the floating production storage and the offloading device,the three-dimensional(3D)multibody dynamics modeling is established by splitting the hinge joints and the field prototype monitoring information.The accuracy of the proposed multibody dynamic simulation method for describing the motions of hinges and single bodies is validated through the redundancy information of field monitoring.Compared with the existing two-dimensional model of SYMS,the 3D model proposed in this paper comprehensively considered the influence of the motions of the hull and mooring structure;the mooring restoring force has an obvious wave frequency effect.Furthermore,the modeling can comprehensively describe the real-time service status,such as motions and postures of mooring components and mooring forces of SYMS.
