| Abstract [eng] |
The report presents the design of a tactile piezo sensor designed to detect and preliminarily determine the intensity of ultrasonic vibrations of the object. This investigation clarifies the usage goals of touch probe sensor in particular situations, operating principle, construction, possibilities and areas of application. The goal of the research was to create a simple, lightweight and ergonomic device that enables quick (with one short touch – up to 1 s) detection and testing of ultrasonic vibrations on objects (ultrasonic concentrators, their interchangeable tips, concentrator mounting structures, device housings, etc.). This tool wasn’t created for precise measurement, but for a quick and reliable detection of the points with minimum and maximum vibrations of vibrating objects and further considerations for detailed measurements. The detection range of this particular piezo sensor identifies vibrations of 20–100 kHz. This is the most commonly used range in ultrasonic vibration systems (UVS). The goal of the study was to optimize the design of probe to be reliable in this frequency range and do not enter into resonances of lower modes of the sensor’s structural elements that could distort the testing results. |
