摘　　要：良好的适应性是仿真系统生命力的重要保证之一。提高仿真的适应性需要规定良好的模型和系统描述规范,并借助于规范的仿真系统开发模型,建立集成的仿真应用环境。基于实时网络的分布式硬实时仿真在很多领域有着广泛的应用,为适合硬实时仿真的需求,将离散事件系统形式化规范进行了适当扩展,并以面向对象模型和数据驱动的仿真系统开发方法为基础,建立了一集设计、试验与分析于一体的适应性集成实时仿真环境。文章详细介绍了硬实时仿真运行支撑件及其辅助工具的具体设计,并以其在“柔性数字化航天器设计”项目中的应用举例验证了该仿真环境的合理性。Distributed hard real time simulation based on memory shared network is widely used in many fields. To better facilitate modeling and simulation development as well as model integration and reuse in this occasion, a flexible cooperative modeling and simulation framework based on data driven methodology and extended DEVS （Discrete Event System Specification） was proposed. Critical technologies of proposed memory shared simulation runtime infrastructure （including communication mechanism, global time management algorithm, etc.） were thoroughly discussed. To verify effectiveness of proposed hard real time simulation environment, a concrete realization of this kind of system was developed and its use in one application named ＂digital spacecraft design platform＂ indicates that it has good simulation adaptabilities and is able to improve model composabilities.
