摘要
隔水套管是石油工程中的重要设备。将隔水套管简化为海底固定、下层平台简支的梁模型 ,考虑Morison非线性流体阻尼及流体涡激力 ,建立套管的振动控制方程 ,并采用多项伽辽金法 ,分别计算了流作用和波 -流共同作用于 170m深水套管的非线性涡激振动响应 。
The casing pipe against the water is important equipment in oil engineering. The vibration control equation of the casing pipe are set up as the casing pipe is modeled as the beam model which is fixed in the bottom and is simply supported at the lower deck, while considering Morison's nonlinear fluid damp and vortex loads. The nonlinear vortex excited vibration responses of 170 m long cas ing pipe are obtained under the current and the wave current employing the Galerkin method. This paper provides the analysis method for strength of a casing pipe.
