为了分析出深海钻机光电复合缆缆的动力特性,从而给光电复合缆的姿态研究和收放缆控制提供可靠依据,将光电复合缆离散成有限个集中质量点,对每个集中质量点进行受力分析,应用牛顿运动定律建立数学模型。利用MATLAB程序计算出了各个集中质量点处的拉力值。得到了不同深度和不同定位半径下缆绳上张力的分布情况。结果表明:利用集中质量法分析出应力分布,可以为光电复合缆的姿态研究和收放缆控制提供可靠依据。
In order to analyze the dynamic characteristics of the optoelectronic composite cable for deep-sea drilling rigs and provide a reliable basis for the attitude research and the retractable cable control of the optoelectronic composite cable, the optoelectronic composite cable is discretized into a limited number of concentrated quality points, and each focused quality point is subjected to Force analysis, the application of Newton’s law of motion mathematical model. Using MATLAB program to calculate the concentration of each point of the pull value. The distribution of tension on the cable under different depths and different positioning radii is obtained. The results show that the stress distribution can be analyzed by using the concentrated mass method, which can provide a reliable basis for the attitude research and the cable receiving and receiving control of the photoelectric composite cable.
