A virtual-reality technology based on 3D Graphics Rendering Engine(OGRE)is proposed to realize the semi-physical simulation of container crane operation training for the issues of low efficiency and poor security in the field of container hand-ing training. It designs the hardware of crane’s cab for operation training. The 3D virtual scene of container yard is rendered by OGRE. It establishes the mathematical model of the spreader flexible rolling system, simulates the residual swing of crane’s spreader. The physical hardware of crane and virtual reality simulation software are communicated by Ethernet for information exchange. This system takes efforts to solve the key issues in the container crane simulation operating system such as the visual software drivers, the residual swing analog of crane’s spreader, the communication between the physical hardware and real-time virtual software. Experimental results show that the semi-physical simulation system has a strong sense of reality. This system has an important practical significance in both normal crane driver training and disposal training in case of emergency.
