要約

Problems related to accelerated tests of structures in relation to resonance are considered. A procedure is proposed that enables improving the accuracy of determining resonance amplitudes of steady-state oscillations. Examples of adjusting resonance amplitudes of structure oscillations with low damping levels are given.
