摘要：
The paper presents the results of investigation aimed at substantiating the approaches to choosing a scheme of fastening structural components to be fatigue tested on the movable table of an electrodynamic vibration exciter. It is demonstrated that an improvement of efficiency of electrodynamic excitation of vibration is achievable in the case of antiphase vibrations of the test component and one of the elements of the component-fastening vibrating system, as well as in the case of a simultaneous optimal mismatch of their natural frequencies. © 2004 Plenum Publishing Corporation.
