Technology for controlling nonlinear vibration phenomena of ultrasound.
Evaluation technology for ultrasonic propagation conditions based on the measurement and analysis of sound pressure data.
The Ultrasonic System Research Institute has developed a completely new dynamic control technology for ultrasound by utilizing two function generators. This technology enables the control of nonlinear ultrasonic phenomena through oscillation (sweep) with two different waveforms. Note: Nonlinear (resonance) phenomena By generating higher harmonics (above the 10th order) through original oscillation control and resonating with low-frequency vibration phenomena, the generation of high-amplitude harmonics has been achieved, resulting in nonlinear (resonance) phenomena of ultrasonic vibrations. By optimizing the ultrasonic propagation characteristics of various components according to their intended purpose, efficient ultrasonic oscillation control becomes possible. Through the measurement and analysis of sound pressure data from ultrasonic testers, this system technology allows for the dynamic control of surface elastic wave changes according to the intended use. Ultrasonic propagation characteristics: 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) 4) Detection of interactions (analysis of power contribution rates)
