Устройство работает следующим образом .The device works as follows.
Колебани виброгенёратора 1 через вибростол 2 и испытуемый образец 3 предаютс пригрузу 4. Колебани пригруза 4 и вибростола 2 с помощью датчиков 5 и 6 ускорений преобразуютс в электрические сигналы, которые усиливаютс усилител ми 7 и 8 и передаютс на блок 9 сравнени . На выходе блока 9 возникает напр жение, пропорпиональное разности ускорений пригруза 4 и вибррстола 2. После двукратного интегрировани сигнала интегратором 10 на егчэ выходе возникает напр жение, пропорциональное величине относительной деформации образца, Которое фиксируетс индикатором 12, шкала последнего градуируетс в единицах относительной деформации. Ивдикатор 11 регистрирует величину усили , приложенного к образцу ,.: По показани м индикаторов 11 и 12 вычисл етс величина динамического моДУТЕЯ уПру1Ч)СТИ.Vibrations of vibration generator 1 through vibration table 2 and test sample 3 are delivered to load 4. Fluctuations of cargo load 4 and vibration table 2 are converted into electrical signals by acceleration sensors 5 and 6, which are amplified by amplifiers 7 and 8 and transmitted to comparison unit 9. At the output of block 9, a voltage arises, the proportional difference between the accelerations of the weight 4 and the vibr stol 2. After the signal is integrated twice by the integrator 10, a voltage appears on the output proportional to the relative deformation of the sample, which is fixed in units of relative deformation. The indicator 11 registers the magnitude of the force applied to the sample.: Based on the indications of indicators 11 and 12, the value of the dynamic modulus is calculated.
