Abstract:

The seizure-preventing for synchronous gears of the Astromesh deployable satellite antenna is studied with random variables and interval variables existing at the same time. The uncertainties with influence on gear pair seizure failure are subdivided into interval variables and random variables, on the basis of which the interval and probability hybrid model is built for the synchronous gear pair seizure failure in the ring truss deployable antenna. The synchronous gear pair anti-seizure reliability is evaluated at different ambient temperatures with this hybrid model. And the results are compared with the reliability evaluated by the probability model in which the uncertainties are all regarded as obeying normal distribution.

Key words: deployable antennas, reliability, interval and probability hybrid model, synchronous gear, seizure-preventing
