a visual simulation system of the high altitude gliding torpedo was researched, and the model was establish accurately. Because the attitude angle of the gliding torpedo changed quickly, and the background parameters were complicated, the problem of rapid change part and separation of the model always was exist, the visual simulation was hard to carried out. The method with combined using DOF and Switch node was proposed. The MATLAB Simulink model was used to calculate the 6 DOF data and save the data through the To Workspace module. Then Vega application program was written by VC++ 6.0, with reading the motion parameters and using LOD technology which couldnt reduce the display speed, the simulation visual effect was also improved. Simulation results show that the system can achieve the specific visual simulation functions and performance requirements for high altitude gliding torpedo, the visual simulation t will never be distorted because of rapid change part and separation of the model. |
