FIELD: measuring technique.
SUBSTANCE: method comprises measuring natural frequency of vibration at m given points, exciting the structure at several frequencies out of the region of the natural frequencies, choosing the observation point A, and measuring the amplitude of change of the observation parameter at each frequency of excitation at each of m given points and at the observation point A. The values of amplitude functions are determined by a special mathematical processing.
EFFECT: enhanced reliability.
