Abstract:

The first applications in power ultrasonics were largely focused on ultrasonic cleaning baths, which rely on generating inertial cavitation, and the incorporation of ultrasonic excitation in manufacturing processes such as joining of plastics and metals. Since the early days of power ultrasonics there has been a rapid growth in the number of applications, and the diversified range of applications, from microwelding to ultrasonic osteotomy, has been made possible by a combination of advances in experimental techniques for characterizing low ultrasonic frequency vibrations and acoustics, and adv

Abstract:

This study employs the transmitter part of an ultrasonic proximity sensor to generate a powerful ultrasonic field for medical humidification. This field is created using an arrangement of small ultrasonic transmitter transducers configured in an acoustic levitator-style setup. As droplets pass through this ultrasonic field, they undergo disintegration, leading to an accelerated evaporation process. The research findings highlight a significant change in droplet size distribution due to ultrasonics, resulting in a notable increase in the rate of evaporation. As a result, this study presents a c

Abstract:

<sec>Researches have shown that a reasonably designed phononic crystal defect structure in high-power piezoelectric ultrasonic transducers can effectively suppress stray vibration modes. However, when the size of the transducer is large, the improvement of the displacement amplitude of the radiation surface of the transducer device by the phononic crystal defect structure is still not so ideal. How to effectively suppress harmful vibrations while ensuring the operational efficiency of transducers and enhancing the displacement amplitude of their radiating surfaces has always been a chall

Abstract:

The vibration characteristics of flexural vibration disk in ultrasonic vibration system are studied through experiments. The results show that the resonant frequency of flexural vibration disk reduces with the reducing of its thickness and the resonant frequency increases with the reducing of its diameter. When designing the ultrasonic vibration system, because the transformer horn and the flexural vibration disk are designedly integrated, the defects caused by the way of threaded connection can be avoided. It is found that flexural vibration is dominating in the disk with some reflected ultra

ABSTRACT At the National Research Council of Canada Industrial Materials Institute, research is in progress on the application of laser-ultrasonics to remote measurement of the thickness of oil on water. Laser-ultrasonics is a novel technique developed for the nondestructive inspection of materials. It uses a short pulse laser for the generation of ultrasonic waves in the oil layer and a second laser, coupled to an optical interferometer, for the remote detection of the ultrasonic surface motion. Direct measurement of the time of flight of the ultrasonic wave provides the value of the thicknes
