锚泊系统的建模与仿真是锚操作模拟器中的关键技术之一,模型的质量和可视化效果将会影响到场景仿真的实时性、逼真度和沉浸感,从而影响到利用模拟器进行抛起锚培训的效果。基于集中质量法建立了锚泊系统的动力学模型,采用四阶龙格-库塔法进行了数值解算,模型解算的速度能够满足仿真的实时性要求;建立了非线性海床土中锚泊线的受力模型,实现了锚泊线与海床土的交互建模,能够反映嵌入海床土中锚泊线的运动情况;采用了一系列可视化技术,实现了海洋工程中锚操作过程的动态仿真及可视化。
The modeling and simulation of mooring system is one of the key technologies in the anchor operation simulator. The quality and visualization of the model will affect the real-time, fidelity and immersion of the scene simulation, which will affect the use of the simulator to throw the anchor The effect of training. The dynamic model of mooring system was established based on the mass-concentration method. The fourth-order Runge-Kutta method was used to solve the numerical solution. The speed of the model solution can meet the real-time requirements of simulation. The nonlinear anchoring Which can reflect the movement of mooring line embedded in seabed soil. A series of visualization techniques are used to realize the dynamic simulation of the anchor operation process in offshore engineering And visualization.
