Abstract
The spacecraft experiences changes of light region periodically and will be seriously affected by the thermal stress caused by the solar radiation. Based on the isogeometric analysis, the random dynamic responses of solar array with random field parameters under thermal-structural coupling are addressed. Firstly, the heat conduction differential equation and vibration differential equation of the solar array are obtained based on the geometric model constructed with non-uniform rational B-spline. The differential equations under thermal-structural coupling are then solved by using Newmark-β method to obtain the structural temperature field and the random dynamic responses. Finally, the influences of different random field parameters on structural dynamic response are investigated. [Figure not available: see fulltext.]
