Ultrasonic oscillation control technology (consulting support)

The Ultrasonic System Research Institute has developed a classification method for the phenomenon of ultrasonic vibrations propagation through the measurement and analysis of ultrasonic propagation states. This classification method estimates linear and nonlinear resonance effects based on the dynamic characteristics (changes in nonlinear phenomena) of the main frequency (power spectrum) related to the ultrasonic propagation state. From previous data analysis, we have been able to categorize effective utilization methods into the following four types: 1: Linear type 2: Nonlinear type 3: Mixed type 4: Variable type Furthermore, the variable type can be further classified into the following three types: 1: Linear variable type 2: Nonlinear variable type 3: Mixed variable type (dynamic variable type) There are numerous successful cases regarding the application of ultrasonic technology based on the development of devices, control settings, and inspections based on the above types. In particular, regarding stability and changes, detailed classification by frequency components has made it possible to efficiently set and adjust various conditions for the intended purpose and effect.

The Ultrasonic System Research Institute has developed a technology for controlling ultrasonic oscillation using nonlinear vibration phenomena caused by surface elastic waves in wire materials. By confirming the basic acoustic properties (response characteristics, propagation characteristics) of various wire materials (stainless steel, copper, resin, etc.), the combination of stainless steel and Teflon tubes enables complex acoustic characteristics. As a result, the desired ultrasonic propagation state can be achieved through oscillation control. Using an ultrasonic oscillation control probe, we set the conditions for sweep oscillation based on the measurement and analysis of the intended purpose and interactions. In particular, to control low-frequency resonance phenomena, we utilize high-frequency nonlinear phenomena. For this purpose, sound pressure measurements require a measurement range of over 100 MHz. The key point is to evaluate the dynamic vibration characteristics of the system based on the measurement and analysis of sound pressure data. We have established and confirmed new evaluation criteria (parameters) that indicate the state of ultrasound suitable for the intended purpose.
