摘要
深海钻机收放过程中,为了得到光电复合缆的合理下放长度,以"大洋一号"科学考察船的万米光电复合缆为研究对象,对收放过程中钻机与光电复合缆相互作用的力学行为进行分析研究,建立光电复合缆的悬链线数学模型。利用Maple软件和Matlab软件进行分析与计算,得到了不同定位半径下光电复合缆的放缆长度及其轴向应力的水平分量。结果表明:建立光电复合缆的悬链线方程得到缆绳长度可为深海钻机的缆绳收放控制提供参考。
10000-meter-long GTTS equipped in the Dayang I scientific research ship were studied to obtain the suitable length unwinded into the water. Based on the analysis of mechanical behavior of the GTTS with the drill, the catenary model of the GTTS were established. The length and the axial stress of the cable under different locating radius were obtained by analysis and calculation with Maple and Matlab software. Results proved that the equation can provide reference in control of unwinding and winding the GTTS.
