The common simulation training system realizes the common design of hardware and software, and also increases the difficulty of group training management. In order to solve the problem of flexible group training of multiple training modes for general simulation training system of a certain type of naval combat system, this paper puts forward a formal description method of group training resources and group training programs based on an in-depth analysis of training management requirements. Design and implementation of a general simulation training system training management software.
在海上作战过程中,空中力量通常使用反舰导弹对舰艇编队进行多批次、多方向的饱和攻击,对舰艇编队的安全构成了极大威胁.因此,对空防御是舰艇编队的主要任务.为了对空中目标进行有效的火力分配和打击,首先要对空中目标的威胁进行分析判断,通过相关参数描述空中目标的威胁程度.针对舰艇编队防空作战中目标数量多、信息量少导致威胁判断和火力分配难的问题,论文以威胁隶属度函数表示目标信息,建立了基于熵值法和TOPSIS的防空目标威胁评估方法,不仅能够较为准确的量化评估空中目标的威胁程度,还能为编队合理分配火力有效对抗来袭空中目标提供依据,提高编队指挥员决策的可靠性,对提高舰艇编队防空作战决策的准确性和科学性有一定的参考价值.
Compared with microwave communication,satellite communication and ultrashort wave communication,shortwave communication although relatively limited communication rate,but with prominent characteristics of long distance communication,simple equipment and strong survivability,is still an important means of military communication at sea. Short wave communication is constrained by the number of channels, ionospheric variations and the influence of electromagnetic interference,communication environment is deteriorating. In order to ensure the reliability of HF military communication,the mathematical model to predict the frequency should be established. The existing shortwave communication frequency prediction models need manual search chart,and unsuited to computer. Based on the existing short wave propagation prediction model,using the International Geomagnetic Reference Field Model( IGRF ),the simple HF transmission loss calculation model is established. This model has been used in the simulation system,and has good effect,and it has good engineering application value.

To deal against considerable equipments and their complicated manipulation in warship like platforms, Functional Simulator conception was put forwards to accord with operation simulation. The architecture design of a functional submarine simulator was introduced. Intelligent maneuver control was implemented based on state equations. Combing sonar equation and off-line calculated data, sonar detection was simulated to process azimuth resolution. Data statistics was employed to determine distribution ellipse for communication indicated target information. Torpedo trajectory was calculated with relative motion principle, and missile trajectory was calculated with analytic geometry theory.Interactive interface was implemented with virtual interface and 3D image generation.
In the virtual training simulation software, users through graphical interfaces to fullfill information exchange. By adopting the method of black box testing, treating the virtual training simulation software as a black box and input data to drive the software running, could test the interaction of graphical interface. The test case generation method based on data flow diagram (DFD), which is characterized to form a complete set of test cases and cover the entire path of the program, could improve the efficiency of the test and ensure the reliability of the test results.
The Military Electronic Equipments Training Simulation Software is a kind of large and complex softw are systems.Its development requires a clear understanding of desired system features firstly.The development of military electronic equipments training simulation softw are exists many problems,such as deficiency in reuse and development.The feature model has been w idely adopted as a domain requirements capturing model by most of the current domain engineering methods.Aiming at these problems,service analysis,function analysis and the behavior analysis are made for this domain.Then the feature model is constructed w hich includes simulation object management,simulation model driven,running suport platform.Practice show s that,based on the feature model,the development platform of military electronic equipments training simulation softw are can fit to the most development of electronic equipment simulation training softw are,and can also get good results.
Bridge-type grab ship un-loader is generally used to unload mineral or coal materials from watercraft.The grab could be controlled to move,open and close in three dimensions,so that the material is grabbed from watercraft and transfer to dock.To simulate the ship un-loader realistically,a series of technical puzzles,including grab motion,dynamical digging,rope slacking,multi-channel stereo scenes and sound impact was researched and solved with physical and mechanical modeling.An immersive training simulator was realized.
