Abstract
A vibration test facility and a test program for the deployed dynamic testing of large flexible solar arrays are described. The results of tests conducted on an array from the Communications Technology Satellite Program are presented. The tests found 8 blanket resonances, 7 array resonances, and the damping coefficients (or the equivalent linear damping coefficients for the resonances that had a non-linear damping coefficient) of 4 of the 7 array resonances. Also, it is observed that certain resonances are excited by subharmonic excitation.
