The Research Of Ballistic Missile Warhead Posture Simulation Software Based On HLA

Distributed simulation can make simulation systems located in different areas interconnected with some acknowledged frameworks, standards, protocols and so on.It is a technology of forming participatory and integrated simulation environment, which can bring about large-scale and complex simulation systems.Meanwhile, High Level Architecture (HLA) is suitable for the interoperability and reusability in distributed simulation system, because it makes function implementation layer, runtime management layer and basic communication layer separated, with the help of universal and independent server programs in RTI (Run-Time Infrastructure) system. At present, HLA is accepted by IEEE as IEEE1516 and becomes the principal standard in distributed simulation developments.Digital simulation is adopted to simulate the flight posture of ground-to-ground ballistic missile warhead in this simulation system, which provides application reference in the aspect of researching missile with the evasion tactics.This system, using the technology of HLA, consists of six industrial personal computers, a RTI server and a switch. The design and implementation of distributed simulation platform based on HLA is introduced in this thesis, in which federate classes,OMT (Object Model Template) and the mutual callings between the federate members and RTI are mainly focused.Data modeling and analysis for inertial component tests is mainly discussed. The model analysis system, which is a subsystem of IMU (Inertial Measure Unit) simulator, is designed and implemented in the architecture of three layers.
