Electromagnetic excitation method of spherical wave propagating axisymmetric in metal space
Main Article Content
Abstract
The problem of the excitation of axisymmetric Lorentz forces and shear waves in a spherical metal half.
The problem is solved in the approximation of the far field using the integral Hankel transform to the radial coordinate. Investigated the influence of the size of the inverter in the existence Lorentz forces on the amplitude-frequency spectrum of the excited waves. A comparative analysis of the energy of longitudinal and transverse waves. It is shown that the transverse spherical waves are dominant on energy. These results constitute the theoretical basis for the construction of a mathematical model of the electromagnetic transducer type with axial symmetry in the mode of excitation of spherical ultrasonic waves.
