摘　　要：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 characteristic of GTTS in deep-sea drilling rig and provide a reliable basis for attitude analysis and retractable cable of GTTS, the GTTS was divided into finite lumped mass points. Through the force analysis on every point, mathematical models were built by Newton＇s laws of motion. The tension of each point was calculated by MATLAB. The tension distributions of GTTS under different depths and radius were obtained. The results showed that using lumped mass method to analyze the tension distribution can achieve the purpose.
