摘要: 海洋结构物始终受到环境干扰,对海洋环境的仿真会显著影响航海模拟器的真实感。基于数值波浪模型生成海洋环境场,并利用SQLite开发实海域数据库通过数据库中获取实际的风,海流和海浪信息来与真实海洋保持一致对环境扰动进行建模,并且将时空变化特征和耦合效应都融入仿真。通过提出的仿真方法再现了真实的航行情况,并利用船载传感器的测量数据进行验证。仿真结果与实测数据吻合良好,说明本方法可以进一步提高海洋模拟器的物理真实感。

Abstract: Marine structures are subject to environmental interference all the time, and the simulation of the ocean environment significantly affects the realism of the marine simulators. The ocean environmental fields are generated by the numerical wave model, and the real ocean databases are developed based on SQLite. The actual wind, current, and wave information are obtained from the databases to keep consistency with the actual sea. The environmental disturbances are modeled and both the spatiotemporal-varying features and the coupling effects are brought into the simulation. The real voyage cases are reproduced by the proposed simulation method. The measured data from the on-board sensors are utilized for validation. The simulation results coincide with the measured data, which could further improve the physical reality of marine simulators.

Key words: marine simulator, environmental disturbances, realistic ocean database, on-board sensors
