Способ имитации безопорного состояния упругих конструкций при динамических испытаниях, включающий возбуждение резонансных колебаний балочной модели конструкции и регистрацию ее собственных форм, отличающийся тем, что на концах модели закрепляют сосредоточенные массы, величины которых подбирают по формулеA method of simulating the unsupported state of elastic structures during dynamic tests, including excitation of resonant vibrations of the beam model of the structure and registration of its own forms, characterized in that concentrated masses are fixed at the ends of the model, the values of which are selected by the formula
где i=1, 2 - номер конца модели;where i = 1, 2 is the end number of the model;m - величина массы;m is the mass value;С - жесткость упругой связи;C is the stiffness of the elastic bond;ω - частота исследуемого резонансного режима.ω is the frequency of the investigated resonance mode.
