Basics of Ultrasonic Cleaning and Case Studies/Problem-Solving [LIVE Broadcast]

Dynamic control of ultrasound to achieve stress relaxation on metal surfaces.

The Ultrasonic System Research Institute has developed a completely new dynamic control technology for ultrasound by utilizing two function generators. By generating oscillations with two different waveforms (sweep), we have achieved a technique to control the nonlinear phenomena of ultrasound. Note: The generation of (10th order and higher) harmonics caused by original oscillation control is realized by resonating with low-frequency vibration phenomena, resulting in the generation of high-amplitude harmonics, which is a nonlinear (resonance) phenomenon 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 application. Practically, multiple (two types of) ultrasonic probes generate multiple (two types of) oscillations (sweep oscillation, pulse oscillation), which create complex vibration phenomena (original nonlinear resonance phenomena), achieving high sound pressure propagation states at high frequencies or low sound pressure levels at frequencies matched to the desired natural frequency.

Combination technology of function generator and ultrasonic probe

The Ultrasonic System Research Institute has developed ultrasonic oscillation control technology that enables the utilization of ultrasonic propagation states above 100 MHz by applying a function generator and ultrasonic probe to ultrasonic cleaners. This is a new application technology for precision cleaning, processing, and stirring, based on the measurement, analysis, evaluation, and technology of ultrasonic propagation states. By utilizing the acoustic properties (surface elastic waves) of various materials, it is possible to control ultrasonic stimulation above 100 MHz to the target object with an ultrasonic output of less than 20 W, even in a 1000-liter water tank. This was developed as an application method for nonlinear phenomena through an engineering (experimental and technical) perspective on elastic waves and an abstract algebraic ultrasonic model. The key point is to confirm the ultrasonic propagation characteristics of the target object, and it is important to set the oscillation conditions of the function generator as a control method for the original nonlinear resonance phenomenon (Note 1). Note 1: Original Nonlinear Resonance Phenomenon This refers to the resonance phenomenon of ultrasonic vibrations that occurs when the generation of harmonics caused by original oscillation control is realized at a high amplitude due to resonance phenomena.

Development of "Control Technology for Nonlinear Phenomena" Using a Small Pump

The Ultrasonic System Research Institute has developed "ultrasonic control technology" that dynamically controls nonlinear phenomena related to ultrasonic propagation by utilizing a small pump for liquid circulation. Nonlinear phenomena are evaluated through analysis using an ultrasonic tester. The complex changes in ultrasound (such as ultrasonic cleaners, ultrasonic probes, etc.) are confirmed through time-series data analysis of sound pressure from ultrasonic oscillation and reception, identifying various interactions. Based on the confirmation of these interactions, the oscillation control conditions using ultrasonic probes are optimized, achieving a dynamic ultrasonic control system tailored to specific objectives. In practical applications, such as ultrasonic cleaning, the ON/OFF control (or control of flow rate and velocity, etc.) of the current liquid circulation device is optimized by considering the ultrasonic propagation characteristics related to the installation state of the device and the surface elastic waves of the target object, including the output, oscillation frequency, and control conditions of the ultrasound. In particular, by utilizing the vibration characteristics of the pump to alternately circulate liquid and gas, new nonlinear effects of ultrasound and microbubbles are realized.

Ultrasonic oscillation (sweep oscillation) system for controlling nonlinear phenomena

The Ultrasonic System Research Institute has developed a technology to control the nonlinear vibration phenomena of surface elastic waves based on the acoustic characteristics of original ultrasonic probes. The key point is the setting of sweep oscillation conditions using two ultrasonic probes (essentially, it cannot be controlled with just one probe for ultrasonic oscillation control. By combining the oscillation settings of the two probes, the occurrence of resonance phenomena and nonlinear phenomena can be controlled). Resonance phenomena and nonlinear phenomena can be controlled within a frequency range tailored to the intended use. In particular, when strong stimulation is required, this is achieved by utilizing low-frequency resonance phenomena (e.g., breaking glass). When high-frequency stimulation is needed, this is achieved by utilizing high-frequency nonlinear phenomena (e.g., 700 MHz stimulation).
