The paper considers the problems of monitoring the metrological support of overall parts in mechanical engineering. The decision to implement the control of large products such as ship’s shaft. In addition, an algorithm for analyzing control results using the Matlab program to assess the state of the object of study is proposing.

Abstract. The paper gives an assessment of the current technical condition of the machine-building industry as a whole in the aviation industry. Its weak sides are revealed. Based on the obtained data and the evaluation of existing methods for diagnosing cyclic mechanisms, an approach of the phase-chronometric method based on precise measurements of time intervals is proposed. A functional diagram of the information-measuring system is presented. The results of modeling the real and ideal operating cycle of the gear-boxes are analyzed.

The paper presents an analysis of the development of wind energy and hydropower in the Russian Federation. The analysis of modern approaches to the diagnosis of wind turbines in the world. The possibility of applying the phase-chronometric technology for renewable energy facilities wind turbines and hydraulic units is substantiating. An example of diagnosing wear during operation of gears and rolling bearings based on a phase-chronometric approach is giving. Multivariate mathematical modeling is presenting on the example of a hydraulic unit. An alternative approach to the application of measuring technologies to support the life cycle of hydropower and wind energy facilities using Neurodiagnostic systems is presented.
