Nonlinear Oscillation Control Technology of Ultrasound ――Sweep Oscillation Know-How――
Development technology for dynamic control systems using ultrasound.
The Ultrasonic System Research Institute has developed a new nonlinear sweep oscillation control technology for ultrasound, utilizing the nonlinear vibration phenomena of surface elastic waves. Regarding complex vibration states: 1) Linear phenomena and nonlinear phenomena 2) Interactions and the acoustic characteristics of various components 3) Sound, ultrasound, and surface elastic waves 4) Low frequency and high frequency (harmonics and subharmonics) 5) Oscillation waveform and output balance 6) Oscillation control and resonance phenomena ... Based on the above, we optimize a new evaluation method for surface elastic waves using a statistical mathematical model based on sound pressure measurement data. Ultrasonic cleaning, processing, stirring, ... surface inspection, ... nanotechnology, ... applied research ... various responses are possible. Propagation characteristics of ultrasound: 1) Detection of vibration modes (changes in autocorrelation) 2) Detection of nonlinear phenomena (changes in bispectrum) 3) Detection of response characteristics (analysis of impulse response characteristics) 4) Detection of interactions (analysis of power contribution rates) Note: "R" is a free statistical processing language and environment. autcor: autocorrelation analysis function bispec: bispectrum analysis function mulmar: impulse response analysis function
