- Technology for controlling nonlinear vibration phenomena through oscillation control of original ultrasonic probes -

The Ultrasonic System Research Institute has developed oscillation control technology based on the acoustic characteristics of probes through the manufacturing technology of original ultrasonic probes. This has evolved into technology for controlling the nonlinear vibration phenomena of surface acoustic waves. The key point is the optimization control method for ultrasonic oscillation control tailored to the propagation characteristics of surface acoustic waves on the surface of ultrasonic elements and their intended use (conditions for combining sweep oscillation and pulse oscillation). To achieve this, it is important to dynamically evaluate the propagation state of ultrasound through operational verification of the ultrasonic propagation characteristics of the original probe (sound pressure level, frequency range, nonlinearity, dynamic characteristics, etc.). In particular, it is necessary to measure, analyze, and evaluate the dynamically changing oscillation characteristics of the ultrasonic probe (or element) and the oscillator (function generator) regarding their transmission and reception characteristics. 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)

Application of sweep oscillation control technology to control nonlinear phenomena of ultrasound.

The Ultrasonic System Research Institute has developed ultrasonic system technology that enables control of ultrasonic propagation states above 1-700 MHz by utilizing a megahertz ultrasonic oscillation control probe for ultrasonic equipment. This is a new application technology based on the measurement, analysis, evaluation, and techniques of ultrasonic propagation states, applicable to precision cleaning, processing, stirring, welding, plating, and more. By utilizing the acoustic properties (surface elastic waves) of various materials, ultrasonic stimulation can be controlled for several tons of target objects even in a 1000-liter water tank with ultrasonic output below 20W. It was developed as an application method for nonlinear phenomena through an engineering (experimental and technical) perspective on elastic wave phenomena and an abstract algebraic ultrasonic model. The key point is the use of tools (elastic bodies: metal, glass, resin). By confirming the ultrasonic propagation characteristics depending on the conditions of the target object, it is important to address it as an original nonlinear resonance phenomenon (Note 1). Note 1: Original Nonlinear Resonance Phenomenon This phenomenon occurs due to the generation of harmonics resulting from original oscillation control, realized at high amplitudes through resonance phenomena, leading to ultrasonic vibration resonance phenomena.
