基于动力定位平台的虚拟仿真系统

Virtual Simulation System Based on Dynamic Positioning Platform

针对船舶动力定位平台控制方式和推力分配纯数字仿真可信度低,难以直观感受动力定位平台航行效果等问题,基于虚拟引擎构建了一套动力定位虚拟仿真平台。平台由虚拟仿真子平台、数值仿真子平台和数据管理系统组成。虚拟仿真子平台实现环境和人机交互、数值仿真子平台实现控制方式和推力分配算法仿真,数据管理系统传输数据驱动虚拟仿真平台,并在虚拟环境中实现动力定位平台的可视化。仿真结果表明,平台可有效地验证航行效果并能合理分配推力,对实验虚拟仿真的可视化设计具有促进作用。

Aiming at the problems such as low credibility of the pure numerical simulation of the control mode,thrust distribution of the ship power positioning platform and the inability to intuitively feel the sailing effect of the power positioning platform,a virtual simulation platform is constructed for power positioning based on the virtual engine.The platform consists of virtual simulation sub-platform,numerical simulation sub-platform and data management system.Among them,the virtual simulation sub-platform realizes the environment and human-computer interaction,the numerical simulation sub-platform realizes the simulation of control mode and thrust distribution algorithm,and the data management system transmits the data to drive the virtual simulation sub-platform and realizes the visual operation of the power positioning in the virtual environment.The simulation results show that the system can effectively verify the sailing effect of the platform and the reasonableness of the thrust allocation,and it plays a positive role in promoting the visualization design of virtual simulation experiments.
