摘　　要：载人飞船回收着陆半实物仿真系统是通过模拟飞船返回压力环境,将回收程控装置硬件实物接入仿真回路的一个半实物仿真试验平台。文章简要介绍了该半实物仿真系统的结构,重点叙述了该半实物仿真系统中特有的负压高精度快速调节压力模拟、多通路指令信号处理、混合式网络、多阶段动力学仿真框架等关键技术。Through simulating pressure environments in process of recovery of spacecraft, and implementing the recovery controlling equipment in the loop simulation,the simulation for recovery and landing system of manned spacecraft was a hardware-in-the-loop simulation testing system. In the paper the structure of this hardware-in-the-loop simulation system was introduced briefly. In the simulation systemthe key technologies, such as negative pressure, high precision and quick adjustment pressure emulator, signal processing of multi-path instruction, composite network, multi-stages dynamic simulation framework, was specified.
