摘要：In order to effectively achieve training goal of under-deepwater emergency maintenance simulation system based on virtual reality, it is crucial to reliably express hydrodynamics as realistic graphics. In the system the operation sets for ROV, crane, winch and ADS's robotic arm are replicas, and ship, tools and equipment, underwater production system and ocean environment are virtual. A series of data conversion techniques and real-time processing framework were proposed that combines finite element calculation with real-time motion simulation in virtual reality. The results show that the research is well handled some key techniques such as multiple persons operating and real-time Human-computer interaction for a large open system, the dynamic coupling of ship-cable-body under marine environment and precise calculation of motion of lowering object in water, coordination of the real-time and accuracy, visualization, different data communication interface technique and so on. The whole system has a strong sense of three-dimensional, realistic and immersive and good scalability. System simulation accuracy is verified within 9.7% by the third party validation. It could provide the inexperienced operators or commanders with wide-ranging second-hand experience so that they can make prompt decisions and quick and precise responses and repairing operations in actual accident situations at low cost aiming to reduce the operational risk.
