Research On The Simulation Of Surface Ship Torpedo Defence System Based On HLA

With the development of torpedo, the serious threat that faces ship is. It is important that how to use the existing weapons to defence the attack of torpedo effectively, especially in developing surface ship torpedo defence system. Using simulation technology we can research rational deployment of torpedo defence in surface ship, which is one of the important methods to research the anti-torpedo technology.Aiming at its simulation requirement, the surface ship torpedo defence simulation system is composed by seven simulation platforms. Since High Lever Architecture (HLA) can meet the need of complex system in large scale, the thesis use COSIM assistant developing tools to develop the surface ship torpedo defence simulation system based on HLA. The main work and achievement are as follows:1. The COSIM platform is comprehended and studied thoroughly. Concretely, the modling rules and the use of softwares in the platform such as run manager and runtime infrastructure are mastered.2. 'According to the workflow of federate, firstly the compoments of federate are designed and function modules of each component are plot out, and then the object classes and interaction classes of federate and data tables of each port in federate are designed. Using the designed state chart and activity chart, the federate can be modled in high level.3. According to the function reqirement of federate, the initial interface of federate is desgined, and then it is further optimized to meet the need of more intelligent. At last, the mathematic models are founded.4. The models in hign level of federate are deduced conceptually, and then the validity and stability of our designed models are validated.5. The distributed simulation platform for surface ship torpedo defence system is developed. The developed platform is an achievement for researching the technology of torpedo defence in surface ship and has been of great value for application.
