Reliability simulation analysis of satellite products

The reliability simulation modeling and analysis of satellite products were studied in this paper. In order to increase the reliability of satellite system, the important products can be design with redundancy structure. Reliability modeling is the basis for satellite reliability engineering. The function and configuration of satellite system is more and more complex, traditional reliability modeling method such as RBD is not applicable. Reliability simulation method can apply to complex system. The reliability simulation method and the basic steps are studied firstly. General reliability simulation models for most products are given, including serial model, parallel model, standby redundancy, voting model. Research is mainly focused on the reliability simulation methods of complex satellite products, such as ring redundancy for TWTAs, more than one redundancy form for gyroscopes, and more than one logic relationship for momentum wheels. Finally, reliability simulation result curves of one satellite system are given as an example.
