Distributed The Last Paragraph Of The Intersection Simulation Study

The research on Distributed Simulation Technology of Last Intersection plays an important role in analyzing how the fuses, the warheads and the targets interac with each others. It can save times of targeting test for weapons on researching, and also can provide operational indicators, technical support to optimize the design and the comprehensive assessment for weapons on pre-research.The entity simulation function and the interactive function between entities in the Distributed Simulation System of Last Intersection (DSSLI) are analyzed. It's also designed that the distributed interactive architecture and the logical framework of the system, including the user interface module, simulation module and engine/interaction module. Finally, the platform for interactive simulation of the last intersection are set up.When the entities simulation function is implemented, to avoid the simulation errors caused by the long frame interval and the simulation frame delay, the algorithms of determining precise location of entities between two frames, single / multi-thread simulation method are studied. Thus, the accuracy of the simulation is ensured. The coordinates of DSSLI is established. And in order to keep consistency with objects in different coordinates, the conversion mechanisms between them is established too. For there are a great deal of the detailed simulation results, the strategy of local storage is adopted to avoid network congestion and low efficiency.When the entities simulation function is implented, the object simulation models in the DSSLI are constructed. Six characteristics models of the target are constructed, two of them is used in the simulation of fuse exploring target and four of them are used in the simulation of warhead destruction. The fuse simulation model is based on the fuse-trigger-line method. Because the traditional method can cause simulation error in a distributed environment, the sampling method based on distance is studied to improve the accuracy of the simulation. The simulation model of destruction effectiveness which is used to calculate the efficiency of target destruction is constructed. And the discussion is based on the example of fragments warhead.Establishes experimental Platform, and develops the DSSLI prototype by using the serial and special development tools made by MAK inc. and VC++ tools. It implements the major function of various simulation entities. Finally, the DSSLI is tested, validated, analyzed and estimated under the flight-test system. The system is already used in...
