On the Assessment of Measurement Results and Their Interpretation to Obtain Information on the Operation of Machines and Mechanisms

The development of methods for obtaining and interpreting measurement data for specific purposes such as the assessment of current technical condition of cyclic machines and mechanisms (CMM), emergency protection, research into the operation of technical installations, control issues, etc. is a topical problem. At present, various methods are used to obtain the data, which indicates the absence of a unified approach to solving problems of CMM technical diagnostics. For example, commonly used amplitude methods do not provide reliable detection of resistant characteristics to assess the functioning of mechanical and electromechanical systems, and the determination of incipient defects and emergency protection. Expert assessments are subjective and depend on the professional level of the specialists, not allowing the adoption of reliable operational solutions to implement control measures and emergency protection. A new phase-chronometric method is proposed for obtaining information on the functioning of CMMs based on a unified complex of precision chronometry devices and mathematical modelling. The phase-chronometric method provides a higher level of metrology and a relationship between the measurement and processing results, and the functioning mechanism elements. This method can also be used to solve problems of the CMM functioning assessment at a higher level.
