深海潜标系统运动仿真研究

Motion simulation study of deep-sea submerged buoy system

利用凝集质量法建立潜标缆索在深海环境中的运动模型,解算张力及缆索构型,采用四阶龙格—库塔法数值解算潜标六自由度运动方程,获得潜标的运动要素与姿态变化.编写Matlab程序进行静力计算与潜标时域动态响应仿真.结果表明,静力计算与动力学仿真模拟结果吻合良好,相互印证静力和动力分析方法及结果的正确性.

The submerged buoy cable motion model was established in deep sea using the lumped mass method to calculate the dynamic tension and configuration of ocean cables.The 4th Runge-Kutta method was adopted to integrate the six degree of freedom motion equation of the submerged buoy system,then movement elements and attitude change were achieved.The static computation and dynamics simulation of submerged buoy were proposed by the Matlab computer program.The results of dynamic simulations are shown to be in fairly good agreement with the static data,which indicate that two analysis methods and conclusions are validated.
