METHOD FOR DYNAMIC TESTING OF STRUCTURES AND SYSTEMS FOR MECHANICAL AND ELECTRONIC EFFECTS Russian patent published in 2019 - IPC G01M7/00 

FIELD: test technology.

SUBSTANCE: invention relates to dynamic tests and can be used in testing mechanical structures for various purposes and electronic equipment for dynamic mechanical or electronic effects. Proposed method of dynamic tests of structures and systems for mechanical and electronic effects is intended for detection of dangerous parameters of test object during testing. Such deviations can not be detected by known test methods. Reason is absence of complete coordination between parameters of the test signal considering its localization on the test object on one side and parameters of the test object taking into account localization of action on it in real operating conditions on the other side. In the disclosed method, this task is solved by using a preliminary alternating percussion excitation of oscillations at n points of the test object and forming, as a result of processing these excitations, n simultaneously operating in the same points test signals of such a different shape, which provides the greatest reaction of the test object at the measurement point compared to other multipoint effects of any other forms, at the same points and with the same energy.

EFFECT: technical result consists in improvement of accuracy and reliability of detection of dangerous deviations of test object parameters.
