Surface modification technology using surface elastic waves of ultrasonic probes.

The Ultrasonic System Research Institute has released a technology that applies measurement, analysis, and control techniques related to the propagation state of ultrasound to alleviate the surface residual stress of ultrasonic transducers using an ultrasonic and microbubble generation liquid circulation system. This technology for alleviating surface residual stress enables improvements in fatigue strength against metal fatigue. In particular, by considering the guided waves (surface elastic waves) of the target object in the propagation state of ultrasound, we have developed a method to realize effective ultrasonic irradiation conditions through settings, tooling, and control. We have confirmed a wide range of effects on various types of metal parts, resin parts, and powder materials.

－－Abstract Algebra Model and Ultrasonic Experimentation and Examination Cycle－－ (Optimization Techniques for Resonance Phenomena and Nonlinear Phenomena) The Ultrasonic System Research Institute has developed ultrasonic <dynamic control> technology that optimizes the interaction of ultrasonic vibrations based on various analytical results of ultrasonic propagation states obtained through an original ultrasonic system (sound pressure measurement analysis and oscillation control) using an abstract algebra model. Note: Control of resonance phenomena (low harmonics) and nonlinear phenomena (high harmonics) is achieved by setting oscillation control conditions based on a logical model. Compared to previous control technologies, this technique establishes and implements optimal control states tailored to the purposes of ultrasonic applications (cleaning, stirring, processing, etc.) through new measurement and evaluation parameters (note) concerning the entire propagation path of ultrasonic vibrations, including various propagation tools. This is a method and technology that can be applied immediately, and we are proposing and responding to it as a consulting service (there is an increasing track record in precision cleaning, stirring, and processing at the nano level). Note: Parameters: Power spectrum, autocorrelation, bispectrum, power contribution ratio, impulse response characteristics, and others.

The Ultrasonic System Research Institute has developed a completely new technology for controlling vibrations using original products (ultrasonic systems). Based on the analysis and evaluation of ultrasonic sound pressure measurement and oscillation control technology developed so far, we perform oscillation control of megahertz ultrasonic waves based on the analysis and evaluation of nonlinear phenomena in ultrasonics. From the accumulation of data measuring, analyzing, and evaluating the dynamic characteristics of ultrasonic waves propagating on surfaces, we apply technology that can <measure, analyze, and evaluate> vibration states from low frequencies (0.1 Hz) to high frequencies (over 900 MHz). Regarding vibrations and noise from buildings and roads, equipment, devices, walls, piping, desks, handrails... the vibrations at the moment of metal melting during welding, instantaneous vibrations during machining, and the complex vibration states of entire manufacturing devices and systems... new countermeasures based on vibration measurement and analysis have become possible. This is a new method and technology, and various application cases have developed from the results obtained so far. In particular, since continuous data collection for a standard measurement time of 72 hours is possible, we can measure and respond to very low frequency vibrations and irregularly fluctuating vibrations.
