FIELD: procedures for determination of dynamic characteristics of a beam assembly at flexural vibrations. SUBSTANCE: the method consists in excitation of resonance flexural vibrations of the beam mock-up of the construction on flexible couplings and registration of vibrations of its own forms. The flexible couplings are selected with a minimum allowable stiffness, at which the linear characteristic of the flexible couplings at vibrations is still ensured, and concentrated masses are fastened on the ends of the mock-ups, their values are selected by calculation. EFFECT: simplified process of tests and enhanced precision of the test results. 1 dwg
