Design And Implementation Of Multi-model Composite Homing Simulation System Based On HLA

Distributed interactive simulations base on High Level Architecture is a hot topic of research in simulation technology. Keeping pace with the latest progress in the control and homing simulation technology, this thesis puts forward an application system framework design on homing simulation system base on HLA. This research is processed in combination with the engineering project:" Multi-model Composite Homing Simulation Platform".For the application in the Multi-model Composite Homing Simulation System, this dissertation first analyzed the base content for HLA and set up an exploitation model base on Federation Development and Execute Process Model. We put forwards the user requirement analysis and performance demand, and carve up the federation member base on the federation function.Base on the composed system frame, this dissertation dissertate about the implement of the functions such as drilling establish, states found and data exchange combined with the MAK RTI and VR-Link.Finally, we discuss the key technology in the Multi-model Composite Homing Simulation System. Time consistency solves the problem of distributed simulation system clock synchronization. First, this dissertation analysis some commonly methods of clock synchronization, then combination with the clock synchronization problem's characteristics of homing simulation system, giving the method of synchronization point registration. To overcome space inconsistent caused by using the difference coordinates. This dissertation presents a mechanism to realize coordinates conversion, and discusses the necessity of coordinates transformation and transformation methods and so on. With Multi-model Composite Homing Simulation System, researched the conversion relationship of coordinates and given the conversion formula. This dissertation put forwards a new framework about data management, and using a dead reckoning technology in the dynamic three-dimensional display.The experimental results indicate that the Multi-model Composite Homing Simulation System features reusable models and expansibility. The results show that the system's performance has been significantly improved. It is a good method to solve the extent of the inconsistency.
