Dynamic Control Method for Megahertz Ultrasound Based on Classification Techniques Related to Ultrasonic Propagation Phenomena

The Ultrasonic System Research Institute has developed a classification method for ultrasonic propagation phenomena based on the analysis results of ultrasonic sound pressure data and changes in the bispectrum. This classification has been applied to Shannon's juggling theorem to develop a "dynamic control method for megahertz ultrasound." This technology is being offered for consulting proposals and implementation support. To utilize ultrasonic propagation phenomena stably and efficiently, it is necessary to examine the response characteristics and interactions related to conditions other than oscillators and transducers, as well as to develop dedicated tools. By examining oscillation waveforms and control conditions, new ultrasonic effects (Note 1: Original nonlinear resonance phenomenon) can be discovered. Utilizing ultrasonic phenomena primarily driven by nonlinear effects according to specific purposes enables highly efficient use of ultrasound. In particular, there has been an increase in achievements in nanolevel ultrasonic technology. Note 1: Original nonlinear resonance phenomenon The generation of harmonics caused by original oscillation control, which is realized at high amplitudes due to resonance phenomena, results in the resonance phenomenon of ultrasonic vibrations.

Optimization technology based on measurement and analysis of ultrasonic propagation of the target.

<Dynamic Control System for Ultrasound> The propagation state of ultrasound is captured as a system, and analysis and control are performed. Many purposes for utilizing ultrasound involve predicting or controlling the nonlinear phenomena of ultrasound propagating through target objects or liquids. However, in many implementations, numerous issues have been pointed out due to the differences between the theory of cavitation and actual results. In response to such cases: 1) To eliminate obstacles, for ultrasound that changes over time, statistical data processing of sound pressure data is conducted, known as <Measurement and Analysis Technology for Ultrasound Propagation State>. 2) Based on the results of data analysis related to the target, the acoustic characteristics of the target are confirmed through <Technology for Detecting Acoustic Characteristics Related to Surface Elastic Waves of Target Objects and Acoustic Flow of Target Liquids>. 3) By confirming the characteristics, progress is made towards achieving dynamic control of ultrasound through <Technology for Controlling Nonlinear Phenomena with Sweep Oscillation Control for Multiple Ultrasounds>. Through these methods, the utilization state of ultrasound has been improved for efficient use, and there are numerous examples of original ultrasound control systems that achieve the intended use of ultrasound.

Nonlinear propagation control technology considering the interaction of ultrasound - Optimization technology for ultrasound -

The Ultrasonic System Research Institute has developed "nonlinear ultrasonic propagation control technology" that takes into account the acoustic characteristics of ultrasonic systems (measuring and analyzing ultrasonic interactions) through the manufacturing technology of sound pressure measurement analysis devices (ultrasonic testers) and megahertz ultrasonic oscillation control probes. With the technology developed this time, it has become possible to achieve dynamic control of ultrasound tailored to specific purposes, based on the measurement and analysis of various interactions involving the target objects, ultrasonic equipment, and tools, through "ultrasonic oscillation (oscillators, transducers, etc.)." Note: Autocorrelation, bispectrum, power contribution rate, impulse response. In particular, by detecting and confirming the interactions between ultrasound and target objects concerning harmonics, effective control for cleaning complex shapes and precision parts (liquid circulation, tools, methods of securing cleaning objects, etc.) becomes clear. Therefore, appropriate selection of ultrasonic frequencies and combinations of transducers with different ultrasonic frequencies can be determined based on the target objects. This is an effective ultrasonic utilization technology tailored to specific purposes for processing, cleaning, surface modification, and promoting chemical reactions.

The ultrasonic sound pressure measurement analysis technology developed so far applies "measurement, analysis, and control" techniques related to the nonlinear phenomena of ultrasound. From the accumulation of data measuring, analyzing, and evaluating the dynamic characteristics of ultrasound propagating on surfaces, we have developed a technology that can measure, analyze, and evaluate vibration states from low frequencies (0.1 Hz) to high frequencies (200 MHz). This technology enables new countermeasures based on new vibration phenomena concerning vibrations and noise from buildings and roads, equipment, devices, walls, pipes, desks, handrails, and the moment of metal melting during welding, as well as instantaneous vibrations during machining.
