A problem about tubing string vibration caused by the fluid unsteady flow inside tubing string is studied from the Angle of solid liquid coupling vibration in dynamics.
文章从动力学中固液耦合振动的角度出发，研究了油管柱内流体不稳定流动引起的油管柱振动问题。
As the VLFS is a long, huge and thin flexible structure, its hydrodynamic response in waves is a typical problem of fluid-solid coupling and it cannot be counted as a rigid body.
由于超大型浮体结构是极为扁平的巨型柔性结构物，所以它在波浪中的动力响应是一个典型的流固耦合问题，不能将其视为刚体。
