MENDELNET <strong>2013</strong>EGGSHELL CRACK DETECTION USING DYNAMIC FREQUENCYANALYSISStrnková J., Nedomová Š.Department of Food Technology, Faculty of Agronomy, Mendel University in Brno,Zemedelska 1, 613 00 Brno, Czech RepublicE-mail: jana.strnkova@mendelu.czABSTRACTThe experimental method of the eggshell impact loading has been used for the dynamic loading ofeggs. This experimental arrangement enables to obtain the impact force and eggshell response. Thework studied the influence of cracks on the dynamical frequency response of eggshells. Fiveexcitation resonant frequency characteristic of signals were extracted based on the difference offrequency domain response signals. These parameters enable to distinguish between intacted andcracked eggs.Key words: eggshell, impact loading, frequency analysis, cracksAcknowledgments: The research has been supported by IP 2/<strong>2013</strong> IGA MENDELU.603 | P age
