Dynamic control experiment of ultrasound using multiple ultrasonic oscillation control probes.
The Ultrasonic System Research Institute has developed a technology for controlling the oscillation of multiple ultrasonic waves by utilizing the nonlinear vibration phenomena of surface acoustic waves. Regarding complex vibration states, the optimization of multiple ultrasonic oscillation controls is aimed at the following items: 1) Linear phenomena and nonlinear phenomena 2) Interactions and acoustic characteristics of various components 3) Sound, ultrasound, and surface acoustic waves 4) Low frequency and high frequency (harmonics and subharmonics) 5) Oscillation waveform and output balance 6) Oscillation control and resonance phenomena (original nonlinear resonance phenomena (Note 1)) ... For the above, we will optimize using a new evaluation method for surface acoustic waves based on sound pressure measurement data and a statistical mathematical model (spectrum sequence (Note 2)). (Note 1) Original nonlinear resonance phenomena The resonance phenomena of ultrasonic vibrations that occur due to the generation of higher-order harmonics through original oscillation control, achieving high amplitude at high frequencies due to dynamic changes over time.

Development of ultrasonic sound pressure data analysis and evaluation technology considering interaction and response characteristics.
We are evaluating the characteristics of ultrasonic equipment according to the purpose of use. <<Analysis and Evaluation of Ultrasonic Sound Pressure Data>> 1) Regarding time series data, we analyze and evaluate the statistical properties of the measurement data (stability and changes of ultrasound) through feedback analysis using a multivariate autoregressive model. 2) The effects of the oscillation part due to ultrasonic oscillation are analyzed and evaluated in relation to the surface condition of the target object through impulse response characteristics and autocorrelation analysis as response characteristics of the ultrasonic vibration phenomenon. 3) We evaluate the interaction between the oscillation and the target object (cleaning items, cleaning solutions, water tanks, etc.) through the analysis of power contribution rates. 4) Regarding the use of ultrasound (cleaning, processing, stirring, etc.), we 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 analysis method is realized based on past experiences and achievements by adapting the dynamic characteristics of complex ultrasonic vibrations to the analysis methods of time series data using ultrasonic measurement data.

The Ultrasonic System Research Institute is applying and developing manufacturing technology for original ultrasonic probes. We have developed technology to control the nonlinear vibration phenomena of surface elastic waves through oscillation control techniques based on the acoustic characteristics of the probes, and we provide consulting services for various ultrasonic utilization technologies. The key point is the optimization of the ultrasonic propagation section (Note). Note: By relaxing and homogenizing surface residual stress, stable ultrasonic oscillation control becomes possible. Setting technology for oscillation control conditions: 1) Setting of oscillation waveforms corresponding to the vibration modes of devices and equipment. 2) Setting of sweep conditions corresponding to the vibration modes of devices and equipment. 3) Setting of output levels corresponding to the vibration modes of devices and equipment. To achieve this, it is important to evaluate the characteristics related to ultrasonic propagation conditions through operational verification of the ultrasonic propagation characteristics of the original probe (sound pressure level, frequency range, nonlinearity, dynamic characteristics, etc.). Ultrasonic propagation characteristics: 1) Detection of vibration modes (changes in autocorrelation). 2) Detection of nonlinear phenomena (changes in bispectrum). 3) Detection of response characteristics (impulse response). 4) Detection of interactions (power contribution rate).
