Design of a System for Mechanical Properties Estimation of Wood using Resonance Analysis

Abstract

The goal of this project is developing a system that could analyze the vibration signals generated by taping the wood samples in order to estimate their mechanical properties for the main purpose of grading. The development of the project was composed of two main parts: the first part integrates develop a software application that receives and analyzes the audio signals and deliver fast and reliable mechanical properties results. The second part addresses perform the non-destructive experiments using the RPi and cheap hardware, it will contribute in introducing a new perspective of measurements. This project is addressed from a double perspective: laboratory based measurements and open field measurements. Besides, it is considered to establish a communication link between this two scenarios for a better diagnosis. The development and implementation of the software application is performed using Python programming and Qt Designer. The software application require from an advanced signal analysis for mechanical properties estimation of wood. The communication link between the two scenarios is established using Python sockets. The result of the exposed culminates with the delivery of a system that estimates the mechanical properties of wood, which complies with the requirements defined in the preliminary stages, and supposes the finalization of the Master.
