The research group "Radiation and Sensing Group" of the University of Alcalá presents a system of non-destructive analysis of materials and structures, by spectral study of the indirect vibroacoustic excitations of the materials analyzed.
By means of this system it is possible to perform in situ the analysis of materials and structures without previous treatments, solving with that the need to use coupling liquids that the current ultrasonic based systems currently use.
The group seeks to reach licensing agreements, collaboration agreements or commercial agreements with technical assistance, with companies from the agrofood, pharmacy, construction, ceramics, wood, cork and other materials sectors.
It is a system of analysis of the properties and defects of materials without specific treatment. That is the case of being able to detect defects hidden in pieces in the own line of production in real time or characterization of chemical and mechanical properties of the materials, roughly or manufactured. In addition, the system is applicable almost any type of material (fluid, solid or composite).
The proposed system consists of an isolated platform that allows the production of vibroacoustic signals by indirect impact on a resonant sheet capable of exciting the materials under study.
The excitation energy of the material is transferred by the impact vibration of a vibrating sheet to audible sound frequencies. The coupling between the material and the vibrating sheet will cause changes in the emission spectral characteristics of the vibrating sheet under normal conditions, whose analysis allows to determine the response of the material and its mechanical, chemical and structural characteristics.
The proposed system is constituted by:
1. A low-cost anti-vibration platform
2. Support structure of vibrating sheet made with the same material as the anti-vibration platform.
3. A square sheet of glass (vibrating sheet) whose vibration frequencies are in the audible range
4. Support platform for the microphone
5. Steel pendulum
6. Condenser microphone or electret
7. PC-type hardware equipment connected to the microphone to obtain the recorded data, with sound and audio processing software.
