The aim of the project is a consolidation of experience with ultrasonic frequency range 0.1 ... 7 MHz to develop scientific and practical basis for the creation of highly effective instrument for EMA inspection, thickness and determine the physical and mechanical properties of materials and eddy current structurescopy. In work was used: methods based on the spectral representation of the device signals the differential and integral calculus, the theory of pulse-forming complex form and their processing and analysis of the formation of acoustic and electromagnetic fields and their interaction with the materials and their boundaries, the process of interaction with the eddy current transducer reinforced monitored. First developed and validated the principle of increasing the sensitivity of EMA testing. The basic factors that influence the results of EMA testing packet of ultrasonic pulses defined limits of their changes, developed methods and apparatus for optimizing their impact in different conditions. Developed and validated the concept of building EMA transducers of different types and applications with improved performance characteristics. Experimentally proved the high efficiency of correlation methods to extract the pulse packet received EMA transducers of noise and interference of various origins. Developed and proved principles of magnetic fields for small EMAT transducers. The technique of the interaction of eddy current transducer with reinforced monitored.
