Abstract

Abstract

The aerospace electric slip ring is a core component of the satellite solar battery array drive assembly. Its reliability is related to the satellite life. Due to the high cost of the space slip ring life test, the long test period and the small amount of sample data, it is difficult to obtain the large-size sample life data. Thus, it is difficult to conduct reliability evaluation using traditional statistical method. In order to solve these issues above, this paper proposes a reliability evaluation method based on friction and wear model. The Hertz theory and heat transfer method are used to calculate the contact area and temperature rising in the process of the friction pair wear, respectively. The effect of thermoelectric multi-field coupling on the friction pair wear is quantified. A multi-physics coupled wear model based on adhesive wear is established. The parameters of slip ring life distribution are estimated using improved Bootstrap method with the life data obtained from the multi-physics coupled wear model. Finally, a series of slip ring reliability indicators are obtained combined with the conventional reliability prediction method. The method comparison results indicate that the improved Bootstrap method provides not only high evaluation accuracy, but also weak subjectivity and flexible applicability. The method evaluation results show that all reliability indicators obtained from the proposed method are in line with the engineering reality, which have powerful application values in practical engineering.
