摘要：

As a payload support system deployed on satellites, the turntable system is often switched among different working modes during the on-orbit operation, which can experience great state changes. In each mode, the missions to be completed are different, consecutive and non-overlapping, from which the turntable system can be considered to be a phased-mission system(PMS). Reliability analysis for PMS has been widely studied. However, the system mode cycle characteristic has not been taken into account before. In this paper, reliability analysis method of the satellite turntable system is proposed considering its multiple operation modes and mode cycle characteristic. Firstly, the multi-valued decision diagrams (MDD) manipulation rules between two adjacent mission cycles are proposed. On this basis, MDD models for the turntable system in different states are established and the reliability is calculated using the continuous time Markov chains (CTMC) method. Finally, the comparative study is carried out to show the effectiveness of our proposed method. © 2023 Beijing Institute of Technology. All rights reserved.
