Abstract

Investigation of natural oscillations for self-deployable truss space antennae V.N. Zimin, I.M. Koloskov, V.E. Meshkovsky, V.I. Usyukin Bauman Moscow State Technical University, Russia Abstract A procedure of dynamic characteristic calculations for a self-deployable truss space antenna, that takes into account the antenna design features, is under consideration. Numerical results for natural oscillations of a space antenna that reflector has dimensions 6x3 m, are shown and compared to frequency test results. 1 Introduction Important problems of modern astronautics are connected with investigation of processes on the Earth and in the Solar System, development of space power units for accumulation of solar radiation and using the energy by mankind, creation of effective space communication systems for remote exploration and ecological monitoring. Development of corresponding space systems is directly related to a possibility of launching large structures in space. As dimensions and
