- Surface modification technology (stress relaxation and uniformity) through nonlinear oscillation control of original ultrasonic probes -

The Ultrasonic System Research Institute has made it possible to control the nonlinear propagation state of ultrasound by utilizing measurement, analysis, and control technologies related to the propagation state of ultrasound as the acoustic characteristics of the target object. As a result, we have developed and advanced technology to efficiently alleviate residual stress on the surface of components. This technology for alleviating surface residual stress improves fatigue strength against metal fatigue and achieves uniformity in various surface treatments. In particular, by considering the guided waves (surface elastic waves) of the target object in the setting and control of the ultrasonic propagation state, we have developed control methods and tools that realize effective dynamic changes in the target object as stimuli that include nonlinear phenomena. We have confirmed a wide range of effects on various types of metal parts, resin parts, and powder materials. This is a new surface treatment technology using ultrasound, which, including the general effects based on acoustic characteristics, can be utilized and developed as a distinctive inherent operational technology for the development of new materials, stirring, dispersion, cleaning, and chemical reaction experiments.

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.

The Ultrasonic System Research Institute has developed ultrasonic oscillation control technology utilizing nonlinear vibration phenomena based on surface acoustic waves. By confirming the basic acoustic characteristics (response characteristics, propagation characteristics) for various targets (water tanks, transducers, probes, jigs, objects, etc.), the desired ultrasonic propagation state can be achieved through oscillation control. By setting the oscillation conditions (waveform, output, control, etc.) with an original nonlinear resonant ultrasonic oscillation probe, we optimize high-frequency propagation states above 300 MHz through high sound pressure resonance phenomena and harmonic generation phenomena (nonlinear phenomena). This technology is an efficient method for utilizing low-output ultrasonic oscillation. The key point is the setting of various parameters utilizing the characteristics of a discrete function generator through digital control. By using the nonlinear resonant ultrasonic oscillation probe, the control range of sound pressure levels due to resonance phenomena is greatly expanded, which is significantly different from conventional sound pressure levels caused by resonance phenomena. Therefore, optimization of control settings based on sound pressure measurement analysis is necessary to avoid phenomena such as damage or destruction.

A technology has been developed to control the nonlinear phenomena of ultrasonic vibrations propagating to the target object based on classification techniques of ultrasonic waves and oscillation control.

We provide consulting services for the development of ultrasonic systems utilizing the following device. <<Deaeration Fine Bubble (Microbubble) Generation Liquid Circulation Device>> 1) By narrowing the suction side of the pump, cavitation is generated. 2) Cavitation causes bubbles of dissolved gases to form. The above describes the state of the deaeration liquid circulation device. 3) When the concentration of dissolved gases decreases, the bubble size of dissolved gases due to cavitation becomes smaller. 4) Through appropriate liquid circulation, fine bubbles (microbubbles) of less than 20μ are generated. The above describes the state of the deaeration microbubble generation liquid circulation device. 5) When ultrasonic waves are applied to the above-mentioned deaeration fine bubble (microbubble) generation liquid circulation device, the ultrasonic waves disperse and crush the fine bubbles (microbubbles), and when measuring the fine bubbles (microbubbles), the distribution of ultra-fine bubbles becomes greater than that of fine bubbles. The above state indicates that ultrasonic waves can be stably controlled.
