Interactive simulation system for totally enclosed lifeboat operations

To address the problems of high cost,operational risk,and significant temporal and spatial constraints associated with traditional lifesaving equipment training,an interactive simulation system for totally enclosed lifeboat operations is designed and implemented in this study. Based on decoupled modeling theory,a four-degree-of-freedom motion model of the lifeboat is established to simulate its dynamic behavior on the sea surface. Numerical modeling and simulation of ocean waves are achieved through wave-spectrum-based generation of unidirectional random waves,thereby reproducing realistic navigation environments for lifeboat operations. Furthermore,a bidirectional data synchronization mechanism is adopted to construct a 2D-3D linked interaction framework that supports multidimensional scenario operations. A three-dimensional virtual environment developed using 3D modeling software and the Unity 3D engine enables immersive scene roaming and interactive equipment operation within the lifeboat simulation environment. Simulation results demonstrate that the proposed system operates stably and provides strong immersion and effective training performance.
