The expediency of introducing dynamic models of defect development into the practice of vibration diagnostics of rotor mechanical units is substantiated. It is shown that as a basis for the creation of models it is advisable to use empirical data. An example of a dynamic model of a small gear defect of a wheel-gear unit is given. The approximate amount of work on the creation of dynamic models is determined. Methods of realization of dynamic models of defects "in the big" are offered.

The urgency of the task of creating test signals of vibration. Described possible ways of implementation of the test vibration signals. A method of forming a test signal by adjusting amplitudes of the individual harmonic components of the vibration signal. Showing the results of modeling. Shows the possible effect of using the proposed method.

In the article the peculiarities and the advantages of using dynamic modes for diagnosing units of rolling stock. Specific examples of the diagnostics of separate units of the locomotive vibration, temperature, electrical parameters, frequency of rotation. The urgency of the task of developing diagnostic systems using the reference models.
