Confront The Underwater Vehicle In The Hla-based Multi-platform Simulation Technology

Keeping pace with the latest progress in the distributed interactive simulation technology, this thesis puts forward a novel blueprint of HLA-compliant Torpedo Weapon Counterwork Simulation architecture. Such pivotal techniques as general federate software framework design, federation synchronization and statistical simulation are investigated. Consequently an underwater counterwork distributed interactive simulation synthesized experimental environment is set up, under which several typical counterwork simulation tests are carried out. This research is processed in combination with the engineering project: "Torpedo Weapon Counterwork Simulation System". The main contributions are as follows:1. A document review is made to analyze the present status and trend of underwater warfare simulation domestic and abroad, research on the aspects of architecture, communication, time mechanism, scalability and interoperability of HLA. This provides a friendly GUI to automatically set time management strategy and publication/subscription declaration and effectively implements consistent interface between RTI and simulation models.2. According to unduly predigesting or not matching of models complexity, a kind of models allocation approach applicable in PC for torpedo simulation is present. In this way, we divide the torpedo model into two parts, one is dynamics models based on six freedoms and another is torpedo self guidance models. The former is as a federate individual, the latter combines with the targets circumstance generation model which separated from targets and decoys models to form the underwater acoustic countermeasure federate. The results indicate that this method improve the simulation accuracy and the real time performance as well.3. Primary factors such as measured error and environmental noises impacted on the simulation results are analyzed. Moreover, experimentation schemes for underwater weapon counterwork simulation system are researched. Statistical Simulation is carried out recurring to the auto reset technology. Technology such as time synchronization, data collection and analysis, simulation replaying is resolved. Finally, under one initial condition, the statistical results are educed These works make a rewarding exploration in statistical simulation based on distributed interactive simulation.4. The time performance of the simulation system is tested. By means of optimizing...
