Reliability Analysis of the Deployment of Astro-Mesh Antenna
The deployment reliability of the Astro-Mesh of a large satellite antenna is investigated. By contrasting the difference of movement principium, a mechanical analysis model is presented. Considering the effects of the randomness of dimensional errors and the space environment factors, the failure models of two performance functions are established by means of the random functional movement method and the second moment method. The corresponding computational expressions for reliability analysis are derived by using the first order second moment method. Furthermore, the theoretical basis and reference are provided for the deployment reliability of a large satellite antenna, and some useful conclusions are obtained.
