Abstract
Спосіб вимірювання напружено-деформованого стану матеріалу за допомогою лазерного допплерівського віброметру включає вимірювання деформації і вібрацій твердого тіла, розкладання вібраційних сигналів у спектральний ряд за допомогою прямого перетворення Фур'є і вимірювання амплітуд гармонік. Вимірювання проводять при неперервному динамічному зростанні навантаження зразка у розривній машині у всьому діапазоні діаграми навантаження, фіксують моменти виникнення вібраційних сигналів у залежності від деформації і визначають кількість перевищень амплітуд гармонік над рівнем дискримінації для кожного вібраційного сигналу, будують залежність кількості перевищень, амплітуд гармонік від деформації, встановлюють відповідність кількості перевищень амплітуд гармонік над рівнем дискримінації з ділянками зміцнення діаграми навантаження зразка.A method of measuring the stress-strain state of a material using a laser Doppler vibrometer involves measuring the deformation and vibration of a solid, decomposing vibrational signals into a spectral series by direct Fourier transform and measuring the amplitudes of harmonics. Measurements are carried out at continuous dynamic growth of the load of the sample in the breaking machine in the whole range of the load diagram, record the moments of occurrence of vibration signals depending on the deformation and determine the number of exceedances of the amplitudes of the harmonics above the level of discrimination for each vibrationform, and establish the number of excesses of harmonic amplitudes above the level of discrimination with the areas of strengthening the chart tazhennya sample.
