| 摘 要： | 在分析地球同步轨道卫星首次变轨任务剖面的基础上,以模块化的思路进行卫星多阶段任务系统(phased-mission systems,PMS)建模,采用基于二元决策图(binary decision diagram,BDD)的静态多阶段任务可靠性分析方法和基于马尔可夫模型的动态多阶段任务分析方法来计算地球同步轨道卫星转移轨道段首次变轨的可靠性。经与传统非任务剖面可靠性分析方法的计算结果比对可知,基于任务剖面的可靠性建模分析方法可得到较为真实和精细的结果,有助于卫星的轻量化设计和研制效益提高。 |

| Abstract: | A modular approach is adopted to model the reliability of the geostationary satellite. The BDD and Markov methods are used separately to analyze the reliability of the static and dynamic modules of the satellite. Comparison of the calculation results with those obtained with the traditional reliability analysis method, shows that with the phased-mission system reliability modeling method, more accurate results can be obtained to provide a reference for the design of the light weight satellite. |
| Keywords: | geostationary satellite phased-mission system(PMS) binary decision diagram(BDD) Markov model mission profile modular modeling reliability |
