Portfolio

We propose a new method for checking the frequency response of strain amplifier used in research and testing in the aerospace industry, in particular in the development of aircraft engines. Traditional methods of verification does not always correspond to characteristics of new strain amplifier and do not always provide the full check. The proposed method is characterized by versatility, extended frequency range, the ability to check the sensitivity of strain amplifier with an error of 0.1%, simplicity. The proposed method was tested on a strain amplifiers used in Motor Sich JSC. The proposed method can be the basis of a automatic test system of strain amplifier. Key words: dynamic strain amplifier, static-dynamic strain amplifier, strength research, frequency response, calibration, octave spectrum.
