The paper deals with dynamics of truss antenna systems with a dynamic absorber in the region of low-frequency natural torsional vibrations. The use of a dynamic absorber is due to the weak dissipative properties of the antenna system. Owing to the internal resonance, energy is transferred from the elastically fixed antenna system to the dynamic absorber, whose vibrations are damped quite simply. A theoretical study of the dynamic characteristics of the absorber was carried out on a simple linear model of a two-degree-of-freedom vibrating system. The equations of motion are integrated numerically. Findings of research show that the mass of the dynamic absorber is about 5% of the mass of the reflector, the absorber should be as far as possible relative to the axis of rotation of the system, and it can be used instead of balancing weights. The ranges of design parameters of the dynamic absorber and the levels of loads at which it operates efficiently are determined
