Abstract :
[en] The objective of this technical note is to explore the applicability of nonlinear modal analysis to spacecraft structures. To this end, algorithms for the continuation of periodic solutions are applied to the finite element model of the SmallSat spacecraft. Nonlinear normal modes and their corresponding frequencies of oscillation are computed, and the results are discussed.
