分析了海洋缆索系统时域三维动态性能,模型中采用了凝集参数法,程序可用于计算海洋缆索的动态张力和动态构型。流速剖面、线内重块、节点推力、航速、水面和海底动态边界都可以模拟,模型还可以模拟具有任意浮性的非均匀列阵,在一套大地惯性座标系下,采用四阶龙格-库塔法数值求解了高度非线性运动方程。采用变曳力系数的模拟结果与试验数据吻合良好。
The three-dimensional dynamic performance of marine cable system was analyzed. The parameters of agglomeration method were adopted in the model. The program can be used to calculate the dynamic tension and dynamic configuration of marine cable. The flow velocity profile, inline weight, node thrust, speed, surface and submarine dynamic boundary can be simulated. The model can also simulate a non-uniform array with arbitrary buoyancy. Under a set of earth inertial coordinate system, Lattice - Kutta method to solve the highly nonlinear equations of motion. The simulation results with variable drag coefficients agree well with the experimental data.
