Ultrasonic processing technology consulting - Control of megahertz ultrasonic oscillation -

The Ultrasonic System Research Institute, in collaboration with Nippon Barrel Industry Co., Ltd., is implementing a "plating method" utilizing ultrasound and fine bubbles for plating treatment. Utilization status of ultrasonic oscillation control probes: - Measurement analysis range: 1 Hz to 200 MHz - Oscillation range: 0.1 kHz to 25 MHz - Ultrasonic propagation range into the plating treatment tank: 5 kHz to over 200 MHz (analysis confirmed) - Oscillation equipment example: Function generator Oscillation method: - Control settings are made corresponding to the acoustic characteristics of the target object. - As a result, by controlling the original nonlinear resonance phenomenon, we achieve ultrasonic propagation states tailored to the purpose. Based on the measurement, analysis, and evaluation of ultrasonic propagation states, this is a new ultrasonic control technology for precision cleaning, processing, stirring, and inspection. By utilizing the acoustic characteristics (surface elastic waves) of various materials, ultrasonic stimulation can be controlled for several tons of structures and machine tools in a 3000-liter water tank with an ultrasonic output of less than 20 W. This was developed as an application method for nonlinear phenomena through an engineering (experimental and technical) perspective on elastic wave motion and an abstract algebraic ultrasonic model.

"Control of Ultrasonic Propagation from 0.1 Hz to 900 MHz" The Ultrasonic System Research Institute has developed a method for controlling the oscillation of ultrasonic probes based on measurement and analysis of the vibration states of various devices and systems. Specifically, this technology involves dynamically controlling the ultrasonic propagation state from 0.1 Hz to 900 MHz according to the intended purpose (cleaning, processing, stirring, welding, plating, etc.), optimizing the resonance phenomena at low frequencies and the nonlinear phenomena at high frequencies. By analyzing and confirming the basic acoustic characteristics (response characteristics, interactions, etc.) of various targets (devices, tanks, transducers, probes, jigs, objects, etc.), it becomes possible to optimize the oscillation control conditions to achieve the desired ultrasonic propagation state. In principle, the oscillation waveform, output, and sweep oscillation conditions utilizing the acoustic characteristics of the ultrasonic probe are optimized to enhance the resonance phenomena and the generation of harmonics (nonlinear phenomena). In cleaning, stirring, and reaction systems, it becomes possible to efficiently utilize a wide range of ultrasonic stimulation through optimized control of multiple ultrasonic probes along with oscillation devices and liquid circulation systems.
