Investigation of the transfer characteristics of ultrasonic tract with electromagnetic excitation and detection of Rayleigh waves in a ferromagnet. Part 2
Main Article Content
Abstract
A closed mathematical model of the ultrasonic path with electromagnetic excitation and detection of radially propagating Rayleigh waves is developed. Calculations of the wave, frequency and pulse transmission characteristics of the ultrasonic path are performed. Shows the effect of radial sizes laying coils as well as the influence of the non-contact value on excitation efficiency of the ultrasonic waves at different frequencies. The recommendations for the design development of the electromagnetic type transducer is given. It is shown that by changing the radio pulse with a varying frequency possible to determine the change of the amplitude frequency response of the ultrasonic path in a wide range of frequencies. The estimation of the duration of the registration process prior to the passage of the cylindrical Rayleigh wave front through the center of the inductor is given.
