摘要:

针对非合作目标抓捕、在轨维护、空间装配等复杂空间操作任务的地面验证需求,构建一套分布式仿真系统,主要由后台仿真模型、前端视景演示系统和前端主控制器组成。为实现不同建模工具或编程语言之间的多学科模型耦合与交互,引入FMI( functional mock-up interface)标准进行系统集成,提高了系统的模块化程度、通用性与可移植性。为充分利用计算资源、提高仿真效率,分布式部署仿真子系统与模块,利用DDS(data distribution service)通信机制实现高效、可靠的数据交互。双臂空间机器人抓捕非合作目标的演示案例表明,该仿真系统能够高保真模拟从远距离导引到近距离操作的全过程,满足实时仿真的要求。

Abstract:

For the ground verification requirements of complex space operation missions such as non-cooperative target capture, on-orbit maintenance, and in-space assembly, a distributed simulation system is developed, which mainly consists of a back-end simulation model, a front-end visual demonstration system, and a front-end main controller. In order to realize the multidisciplinary model coupling and interaction among different modeling tools or programming languages, the functional mock-up interface (FMI) standard is introduced for system integration, improving the modularity, generality, and portability of the system. To fully utilize computing resources and improve the simulation efficiency, simulation subsystems and modules are deployed in a distributed manner, and the data distribution service (DDS) communication mechanism is used to achieve efficient and reliable data interaction. A demonstration case of a dual-armed space robot capturing a non-cooperative target shows that the simulation system can simulate the whole process from long-range guidance to close operation in real time, with high fidelity.

Key words: simulation system, space operation, functional mock-up interface(FMI), spacecraft, on-orbit service
