The objective of the dissertation is to develop methods and instruments for the measurement of the diagnostic parameters for specific rotary systems, asses their metrological characteristics, and implement practical applications. This work is dedicated to the investigation of three rotor systems. Specific measurement systems are proposed for the measurement of the diagnostic parameters of these rotor systems. The hardware designs and signal processing algorithms are described. The uncertainty analysis of these systems are performed. The proposed systems were developed and used as instruments for the research of specific rotary systems. The possibilities for the compensation of an aerodynamic imbalance with the mechanical imbalance was described. The methods for assessment of blades inequality in working mode were proposed. The analysis of autogyros rotor and cabin vibrations magnitude and frequency spectrum revealed the impact of rotor balancing and aerodynamic conditions on the vibrations level. The assessment of paper folding machine working segment rings quality was performed. |
