Technology for optimizing the resonance and nonlinear phenomena of ultrasonic vibrations through megahertz oscillation control of an original ultrasonic oscillation control probe.

By confirming the basic acoustic characteristics of ultrasonic waves (response characteristics, propagation characteristics) for various targets (water tanks, transducers, probes, fixtures, objects, etc.), we realize ultrasonic propagation states tailored to specific applications through oscillation control. Using two or more types of nonlinear resonant ultrasonic oscillation control probes, we dynamically control high-frequency propagation states above 900 MHz through the setting of oscillation conditions for sweep oscillation and pulse oscillation (note), resulting in high sound pressure level resonance phenomena and the generation of harmonics (nonlinear phenomena of 10th order and above).

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.
