在过去的30年里，随着电源、电枢和轨道的发展，许多类型的电磁发射系统被建造用于科学研究或军事应用。系统级仿真为更好地理解电磁发射装置的工作原理和评估不同用途电磁轨道炮的综合性能提供了有力的工具。在本文中，我们提出了一种新的仿真方法，以提供更快和可扩展的仿真各种轨道炮。为了更生动地反映操作细节，更好地利用仿真结果，对仿真平台的功能和结构进行了研究。提出了面向对象建模、分布交互仿真、虚拟现实和仿真过程管理等关键技术，有效地保证了模型的重用、仿真过程的可视化和仿真过程的可控性。然后，在高层体系结构框架下，将仿真平台作为联邦进行开发.通过对两种不同推进元件的电磁轨道炮系统的对比，验证了所提出的方法和平台的优越性。仿真结果表明，等离子体电枢轨道炮对弹丸的加速效果明显优于电枢轨道炮，但对钢轨的损伤更严重。同时，该平台以曲线和场景的形式实现了发射过程和仿真结果的可视化。该仿真方法为现有仿真系统的互操作提供了方便，为实现更大规模的科学研究或其他应用的仿真奠定了基础。
With the development of power, armature and rail, many types of electromagnetic launcher systems were built for scientific research or military application over the last 30 years. System-level simulation provides a useful tool to better understand electromagnetic launcher operation and evaluate the comprehensive performance of railgun for different purpose. In this paper we present a novel simulation approach to provide faster and scalable simulation for various railgun. To reflect more vivid details of the operation and make good use of the simulation results, the function and structure of the platform are studied. The key technologies including object-oriented modeling, distributed interactive simulation, virtual reality and simulation process management are presented, which can efficiently ensure model reuse, visualization of railgun operation and control of the simulation process. Then, the simulation platform is developed as a federation within High Level Architecture framework. The advantages of the proposed approach and platform have been demonstrated through the comparison between two railgun system with different propulsion component including solid metal armature and plasma armature. Simulation results show that the plasma armature railgun accelerates the projectile to velocity in excess of the other one, but causes more serious damage on rail. Meanwhile, the visualization of the launch process and simulation results is accomplished in the form of curve and scene by the platform. Furthermore, the simulation methodology makes it convenient to interoperate existing simulation system and lays foundation for the implementation of larger scale simulation for scientific research or other applications.
