Abstract

Experimental investigation of natural oscillations of space self-deployable frame structure V.N. Zimin, I.M. Koloskov, V.E. Meshkovsky Bauman Moscow State Technical University, Russia Abstract Technique of normal modes analysis for space self-deployable frame structures is under consideration. Results of experimental investigation of dynamic characteristics for a space antenna without radio-electronic devices are shown. The antenna reflector had dimensions 6x3 m. A similar antenna was mounted on the unit "Priroda" of the space orbital station "Mir" and intended for the Earth monitoring. 1 Introduction The most difficult problems that have to be solved during creation and adjustment of space structure are dynamic problems connecting with movement stability, dynamic load determination and strength of structure. Large space self- deployable antennae being a part of space vehicles or orbiting stations often form their low-frequency spectra. The main task of dynamic investigatio
