The article is devoted to development of measuring instrument of parameters of ultrasonic vibrating system. The block diagram of the designed device and the measurement procedure are described. The article presents the results of the measurements carried out by developed device.
This article is devoted to development of new method for vibration amplitude control, which is able to provide continuous measurement during ultrasonic technological processes. Thus, it is possible to control mechanical vibration amplitude of the radiating surface measuring part of electric current flowing through piezoelectric vibrating system. The experimental researches have confirmed efficiency...
The device intended for measurement of depth of hole is described, the block diagram of the device is depicted, as well as the new method of processing echo-signals is offered and analyzed to reduce measurement error.
The information on possibilities and specificities of usage of a noncontact stroboscopic measuring method of amplitude is presented in the article. Results of the stroboscopic method comparison with measuring by means of a hour-type displacement measurer are presented. The carried out analysis allows determining advantages and disadvantages of examined measuring methods.
Ultrasound is a valuable tool for the detection of damage in structures and the characterization of material properties. Its detection is conventionally done by piezoelectric transducers, however fiber-optic sensors can operate over a greater range of frequencies and also yield information on the direction of wave propagation. The interaction between fiber sensors and ultrasound both demonstrates...
