frequency spectrum

Determining the frequency characteristics of the elastic element dynamic quencher fluctuations.

The paper deals with the application of a new method of stress state analysis for the specified influence of the layered beams with masses on their dynamic characteristics. The proposed theoretical model takes into account layer deformation considering a transversal displased deformation, general deformation and strain. Numerical examples are under discussion: the frequency spectrum and damping dependence from the anisotropy of mechanical properties of layer beams. The results are used for optimal design of dynamic quencher fluctuations.

Investigations of Cavitation Processes in Different Types of Emitters Using Sonochemical Analysis

The application limits of optical and sonochemical methods to determine the sizes of cavitation bubbles and their derivatives have been analyzed. The effect of cavitation fields generated using an ultrasonic magnetostrictive oscillator and jet hydrodynamic emitter on the parameters of their acoustic signals has been examined. The bubbles size depending on emitter type and parameters has been determined using sonochemical analysis. The character of the dependence was estimated according to Minnaert formula.
