The article is devoted to determination and study of quantitative index of over-assessment of microaccelerations which are caused by oscillations of big elastic elements. Model of spacecraft elastic element is based on the model of Euler-Bernoulli beam in considered estimation. The results of current article can be applied to determine store of estimation of microaccelerations based on the analysis of beam’s oscillations, to take constructive decisions to provide established microacceleration level in the area with technological equipment, and to estimate appropriateness to conduct some or other gravity-sensitive process on the board of certain spacecraft.
