The most important quality indicator for fruits is the flesh firmness which is highly correlated to the Young's modulus. In this paper, the Young's modulus of a Conference Pear is determined using the results of an experimental modal analysis. A system identification technique in the frequency domain is used to obtain experimentally the eigenfrequency and the damping ratio of the bending mode, the compression mode and the oblate-prolate mode of a Conference Pear. An image processing technique is used to construct a finite element model of the pear. By updating the eigenfrequencies of this finite element model, the Young's modulus of the pear can be estimated. By repeating this procedure during the storage of the pear, one can monitor the quality of the fruit during time and evaluate different storage techniques. |
