Abstract：Here, we consider free oscillations of a structure made up of rigid bodies interconnected by elastic segments under the assumption that the centers of mass of rigid bodies are not on neutral lines when the elastic segments are not deformed. It is assumed that the rigid bodies of the system make a straight motion in the same plane and that their centers of mass are in that plane. Also, it is assumed that the elastic segments belong to the class of Euler-Bernoulli beams. The aim of this paper is to expand the existing results for the case of free oscillations of the mentioned systems of rigid bodies interconnected by elastic segments. This research is of computational importance in systems with many elastic segments and rigid bodies.
