FIELD: mechanical engineering.
SUBSTANCE: method allows determining of resonant frequency, Q-factor, amplitude of stationary oscillations of object and level of exciting influence during exploitation without making influence onto mode of operation of object, without stops and delays at resonant frequencies. Method also allows determining all the factors mentioned above during process of starting and stopping. Procedures of the method can be easily automated for making measurements which results to reduce time and qualification of explorer for measuring necessary parameters. Resonant frequency area (fl, fu) of object is selected. During operation, when object is subject to exciting influence, frequency of exciting influence and parameter of oscillations of object are measured and registered as function of time F(t) and x(t) under the condition that the frequency of exciting influence belongs to resonant frequency area (fl, fu) and is close to permanent level of exciting influence. Value of exciting influence E0, amplitude of stationary oscillations Ap, resonant frequency fp and q-factor are judged from registered values of exciting influence frequency F(t) and parameter of oscillations of object x(t).
EFFECT: reduced chance of damage during operation.
