Modelling of Ultrasonic Concentrators for Processing of Volume Nanostructured Materials

Abstract:

The article is devoted to studying of stress and displacement amplitude distribution in ultrasonic concentrators of different forms. The modelling of different forms of ultrasonic concentrators was considered in detail that allowed to choose an optimal form of concentrator providing maximum amplitude of vibrational speed and uniform stress amplitude distribution across the concentrator section. The modelling was carried out for purpose of the subsequent application of ultrasonic treatment to nanostructured materials. Numerical calculation in the environment of MatLab is carried out and diagrams of dependences of stress and displacement amplitude distribution of conic, exponential, ampoule and two-ampoule forms of concentrators are constructed. Visual distribution models of stresses on the section of concentrators and elastic displacements of material in samples of these forms are constructed, resonance frequencies of longitudinal fluctuations of ultrasonic half-wave concentrators are found in the program Abaqus complex.
