Technology for controlling nonlinear phenomena of ultrasound (acoustic flow)
The Ultrasonic System Research Institute has developed ultrasonic cleaning technology that enables control of acoustic flow (ultrasonic propagation state) in the range of 1-100 MHz by utilizing a megahertz ultrasonic oscillation control probe for ultrasonic cleaners. This is a new application technology for precision cleaning, processing, and stirring based on the measurement, analysis, evaluation, and technology of ultrasonic propagation states. By utilizing the acoustic properties (surface elastic waves) of various materials, ultrasonic stimulation can be controlled even in a 1000-liter water tank with an ultrasonic output of less than 20W. It was developed as an application method for nonlinear phenomena through an engineering (experimental and technical) perspective on elastic waves and an abstract algebraic ultrasonic model. The key point is the use of tools (elastic bodies: metals, glass, plastics). By confirming the propagation characteristics of ultrasonic waves based on the conditions of the target object, it is important to address it as an original nonlinear resonance phenomenon. We believe that this technology can be applied in various fields and are implementing proposals in various consulting services.

basic information
<<Measurement and Analysis of Ultrasonic Sound Pressure>> 1) Regarding time series data, we will analyze and evaluate the statistical properties of the measurement data (stability and changes of ultrasonic waves) through feedback analysis using a multivariate autoregressive model. 2) The effects of ultrasonic oscillation on the oscillation part will be analyzed and evaluated in relation to the surface condition of the target object through impulse response characteristics and autocorrelation analysis, as an interaction of ultrasonic vibration phenomena. 3) The interaction between the oscillation and the target object (cleaning items, cleaning liquids, water tanks, etc.) will be evaluated through the analysis of power contribution rates. 4) Regarding the use of ultrasound (cleaning, processing, stirring, etc.), we will analyze and evaluate the dynamic characteristics of ultrasound based on the nonlinear phenomena (results of bispectral analysis) of the target object (propagation of surface elastic waves) or the ultrasound propagating in the target liquid, which are the main factors of the ultrasonic effect. This analytical method is realized based on past experiences and achievements by adapting the analysis techniques of time series data to the measurement data of ultrasound, enabling the analysis of the dynamic characteristics of complex ultrasonic vibrations.
