As the end point of power delivery, a distribution system is directly connected with the consumers. It has complex structures and various operation modes which make the reliability even more important. However, the traditional FMEA cannot be applied to the complex distribution system which contains ring networks. Taking the capacity constraint of distribution system into consideration, this paper...
According to the necessity of reliability analysis for satellite system subjected to common-cause failures, the unreliability expression under a variety of common-cause condition is developed to analyze the unreliability of satellite system in this paper. Based on static fault tree analysis of satellite system, the binary decision diagram is used to evaluate the reliability considering common-cause...
The reliability analysis of tracking, telemetry and command (TT&C) system is very important for performing space mission successfully. Essentially, the TT&C system can be regarded as a phased-mission system (PMS). In this paper, Markov approach is used to construct a distinct model for each phase of the system and a separate evaluation for each of these models. This paper shows: (1) a method...
Reliability is a measure of an important weapons system performance indicators, is also an important factor affecting system performance. In explaining the basic reliability and reliability model based on the concept, the establishment of portable air defense missile weapon system reliability model, from the specific requirements of reliability design, combined with portable air defense missile weapon...
To overcome the limitation of traditional reliability analysis methods in coupled cases of high-cycle fatigue and low-cycle fatigue and accurately analyze the stochastic fatigue reliability of component, a new kind of method decoupling method for high-cycle fatigue and low-cycle fatigue is firstly put forward. The stress and strain spectrums are corrected and classified. As for high-cycle fatigue,...
When there is limited objective failure data, a method for developing the possibility distribution by subjective assignment strategies is put forward, which is illustrated by the lifetime data from fatigue reliability tests. Based on a limited fatigue life data, a study on reliability analysis of 40 axle-steel is presented, by constructing the possibility distribution function of the locomotive axle...
As the end point of the power system, a distribution system directly connects with the consumers. The reliability of power supply is directly related with consumers. However, uncertainty of the original parameters of components may be caused by lacking of statistical information and the statistic error. It will inevitably produce large errors if we directly use these parameters for evaluation. The...
