The problem of rational selection of the electrohydraulic vibration exciter for vibration tests of a beaming is considered. Trials are carried out{conducted} by structural loading by a harmonic moment of flexion in a condition of a resonance. Formulas for definition of values of power of the vibrator and coordinates of his{its} connection with a design at which the level of structural loading is ensured greatest possible for the given system "design - vibrator" at use of limiting{marginal} capabilities of the vibrator are obtained. Operation is carried out at a support of the Russian Fundamental Researches Fund (the design No 06-08-01005).
