Visual Simulation System Designing Study On Floating Crane

Floating crane is the essential engineer vessel in the ocean engineering, which plays anirreplaceable role in ocean platform installation, large bridge construction and ocean energyresources development, etc. The process of lifting on the sea is extremely complex andmulti-system collaborative, advanced virtual reality technology was used to build the visualsimulation system of ocean lifting. not only is it able to meet the functions of ocean liftingoperation, staff training, program previews and so on; but also it can solve the problems ofhigh-risk, high-cost to a certain extent. Moreover, it can reach the aims at improving operatingefficiency and enhancing operational security.In this paper, the author designs simulation training courses based on the actual process ofocean lifting and the actual operations. Then, taking the actual needs of the trainees intoconsideration, the author builds the ocean lifting operation semi-physical simulation trainingsystem. The system adopts HLA framework model and is made up of integrated managementsystem, multi-channel visual system, the coach system, semi-physical operating system,mathematical model system, user’s interface system, dynamic positioning system, etc.This paper focuses on the following areas:1. Providing users with realistic,high-immersive and real-time virtual scenes by designing and developing the visual modulesof the simulation system, which includes floating crane, auxiliary ship, ocean-atmosphereenvironment, lifting, the main crane and the auxiliary crane, ect;2. Designing the simulationsystem of Human-Computer Interaction in the implementation process, including cranelifting and slewing, sling(flexible) swinging, floating crane6DOF motion;3. Realizing thedata communication of visual module’s, it includes communicating the data of ships, crane,lifting, etc with dynamic positioning, mathematical model, semi-physical operating systemand so on;4. Designing the simulation system of Human-Machine interaction.At last, this paper applies the real data from the ship to test the whole simulation system.The results show that the simulation system can successfully fulfill the entire task of thelifting operation. The system runs smoothly, the vision effect is realistic and the behavior ofmotion is authentic and it achieves the expected goals.
