Abstract EN
Successful unfolding in the space is the first step for a satellite antenna to work normally, so that it is important to study the movement reliability of a large deployable satellite antenna.
By studying the movement principium, a mechanical analysis model of the deployment mechanism and calculating formulae for the internal forces of trusses were presented.
From the performance function of the truss unfolding to meet, a movement reliability analysis model of the mechanism was also given.
Synthetically considering the dimension errors and the impact of space environmental factors, we treated the mechanism's movement as a function of random variables and derived the reliability calculation formula by using the method of second-order moment.
Finally, the movement probability of the deployment mechanism was simulated by the computer within whole spreading process.
The trend of the computing results agrees with the truss model experiments, which shows that the method is reasonable and effective.
