Research of vibrations of structure elements of the space station on video information
Abstract:
Video information about vibrations of elements of ISS structure allows to establish quantitative characteristics of these vibrations. Such characteristics are found as a result of processing of time series obtained by digitizing of video film shots. Digital data are vertical and horizontal coordinates, expressed in pixels, of some points on a station structure element in a shot. Processing of the time series allows evaluating the real time dependence of the coordinates. This dependence in common has an oscillation character and can be presented by the sum of eventual number of simple harmonics, their amplitudes and frequencies being determined by means of spectral analysis.
