| With the continuous development and expansion of marine transportation, improving ship self-handling equipments'loading and unloading capacity can not be ignored, ship crane's operating environment is complex and harsh, it needs a high technical requirements, and difficult to control, often because of unskillful handling produce accident, so operators'proficiency and job security during the operation is particularly important. In order to solve this problem, the subject starting from develop and establish a visual simulation system of ship crane manipulate cabin training,simulate the process of loading and unloading ship cargoes, test the feasibility and safety of loading and unloading, so as to solve problems of ship cargoes'loading and unloading.The issue made a more detailed analysis for the physical system of ship crane, creating a dynamic model of the crane. In the process of simulation modeling, the research based on"Multigen Creator"adopted one modeling method which many kinds of software are combined, successfully created a wharf terrain, three-dimensional model of the crane and achieved the constructing of ship model complex curved faces, and came up with a model format conversion method between engineer modeling software and simulation modeling software. This paper analyzed the dynamic model when ship crane is working, and established visual simulation system for simulating cargoes hoisting in control module. At last, this paper taking"Vega"as developing environment, taking VC++6.0 as software editing platform, expounded the method of constituted virtual simulation system.The results show that the ship crane manipulate cabin training visual simulation system based on virtual reality were able to simulate a operator control the hoisting process of the ship -cargoes in the manipulate cabin, the simulation system better reflects the actual situation of hoisting goods, the conclusions could provide an important basis for the training of ship crane operators. |
