Abstract:

The assembly process of satellite antenna deployable mechanism is complex and mainly depends on manual adjustment. The reliability and safety risk factors in the assembly process are numerous and mutually coupled, which directly affect the quality and efficiency of antenna assembly. Therefore, an approach of probabilistic risk assessment based on Bayesian networks is proposed. Firstly, based on the comprehensive identification of risk factors in the assembly process, the event tree model is constructed, and an intermediate event reliability model of man-machine-environment coupling is established by Bayesian network. Then, human reliability and other methods are used for model quantification and uncertainty analysis, and sensitivity analysis and risk importance ranking are carried out. Finally, the engineering applicability of the proposed method is illustrated by taking a certain type of spaceborne synthetic aperture radar (SAR) antenna deployment mechanism as an example, and the method can provide a reference for risk analysis and quantification of man-machine coupling system such as spacecraft and launch vehicle.

Key words: spaceborne antenna, assembly, man-machine-environment coupling, probabilistic risk assessment, Bayesian network
