We present some results of an investigation of natural and forced oscillation of a space vehicle spatial structure for the case of harmonic excitation due to imbalance of rotors of electric momentum orientation motors with consideration for lumped masses and damping in the material. The investigation was carried out on the basis of the finite-element method. Our results are used in the pilot project.
