Description
Известны способы измерени динамических модулей упругости материалов . Однако такие способы применимы не дл всех частот.Methods are known for measuring the dynamic elastic moduli of materials. However, such methods are not applicable to all frequencies.
В описываемом способе дл увеличени числа измерений и расширени диапазона измер емых частот измерени производ т путем определени частот резонанса и антирезонанса подвижного столмка на котором укреплен образец.In the described method, in order to increase the number of measurements and expand the range of measured frequencies, measurements are made by determining the resonance and antiresonance frequencies of the movable column on which the sample is fixed.
На фиг. 1 и 2 изображены схемы устройства, примен емые при измерении динамических модулей.FIG. Figures 1 and 2 show device diagrams used in measuring dynamic modules.
Способ измерени динамических модулей упругости состоит в том, что через катушку / силового электродинамического возбудител колебрнттй 2 пропускают ток звуковой частоты от генератора 3. Катушка / перемещаетс в поле магнита 4 и вместе с ней движетс измерительна катушка 5 второго электродинамического возбудител 6, св занна с катушкой / жестким стержнем 7. В катушке 5 при ее перемеш,ении з поле магнита 8 возникает э.д.с. пропорциональна по величине и по фазе скорости движени . К столику 9 колебательной системы W, прикрепленному к стержню 7, приклеивают испытуемый образец//, который нагружают грузом 12, имеюшим определенную массу.The method for measuring dynamic elastic moduli is that the oscillator 2 is fed through the coil / power electrodynamic exciter 2 by the oscillator 3. The coil / moves in the field of the magnet 4 and the measuring coil 5 of the second electrodynamic exciter 6 connected to the coil moves with it / with a rigid rod 7. In coil 5, when it is mixed, an emf is generated in the field of magnet 8. proportional in magnitude and in phase to the speed of movement. The test specimen // is glued to the table 9 of the oscillatory system W attached to the rod 7, which is loaded with a load 12 having a certain mass.
Резонансные и антирезонансные частоты колебаний столика 9 определ ют с помощью лампового вольтметра 13, измер ющего э.д.с. в катушке 5. Определив максимальную скорость движени столика 9, что соответствует резонансу, и минимальную скорость, соответствующую антирезонансу , вычисл ют значение динамического модул упругости испытуемого образца //.The resonant and antiresonant frequencies of the table 9 are determined using a lamp voltmeter 13, measuring the emf. in the coil 5. Determining the maximum speed of the table 9, which corresponds to the resonance, and the minimum speed corresponding to the antiresonance, calculate the value of the dynamic modulus of elasticity of the test sample //.
Описываемый способ позвол ет упростить методику проведени испытаний и повысить точность результатов№ 142(372 Предмет изобретени The described method allows to simplify the test procedure and improve the accuracy of the results No. 142 (372
