Abstract:

 The accurate dynamic model of a solar wing is built on basis of its ground modal test, through which the method of the on-orbit load analysis of solar wing is put forward based on its flexible characteristics and modal synthesis hybrid coordinate dynamics modeling. The load analysis of the typical cases such as the orbit changing, module separating, and rendezvous and docking is calculated, the effect of the dynamic performance of the solar wing on the on-orbit load is analysed, and its maximum load is validated through the related test. The test results show that the research method is reasonable and valid, and can be extended to other types of solar wing load analysis.

Key words:  Flexible characteristics, Solar cell, On-orbit loading, Separation, Docking
