METHOD OF DYNAMIC TESTING OF STRUCTURES AND SYSTEMS ON MECHANICAL AND ELECTRONIC EFFECTS

摘要

FIELD: testing equipment.;SUBSTANCE: invention relates to the field of dynamic testing of structures and can be used in tests of mechanical structures and electronic systems on dynamic mechanical or electronic effects. The proposed method of dynamic testing of structures and systems is designed for detection during the tests of dangerous parameter deviations. In the proposed method using the prior shock vibration excitation the object is loaded and the test signal is obtained by the excitation processing, which power distribution and the phase structure of the spectrum is fully consistent with the characteristics of the test object. All the frequency components of the test signal provide the greatest possible response of the test object, as a result of the inphase mutual addition of all the frequency components of the response at the end of each test pulse.;EFFECT: obtaining a test signal coherent with the characteristics of the test object, and the possibility of detecting a dangerous unpredictable system response to the test signal.;2 dwg
