Holographic interferograms of a vibrating thin piezoceramic disk resonator under asymmetric point-mass loading
V. A. Titov Volgograd State University
Abstract:
Deformations of the base of a free piezoceramic resonator that represents a thin disk are visualized using holographic interferometry under high-intensity electric excitation at antiresonance frequencies of radial modes. Motion of a loading point mass along the radial coordinate is used to specify identification of partial modes and the total number and energy interaction of such modes. Four topologically compatible modes form a single mode on which the pattern of Lamb modes is superimposed under certain experimental conditions, and an implicit piston mode is obtained.
