PT - JOURNAL ARTICLE AU - Nedomová, Šárka TI - Response of the potato tubers to impact loading DP - 2014 Oct 11 TA - Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis PG - 63--72 VI - 57 IP - 4 AID - 10.11118/actaun200957040063 IS - 12118516 AB - The response of tubers of nine varieties of potatoes to the bar impact have been evaluated. The proposed method enables to obtain force - time record. The response function is represented by the time history of the surface displacement. This function has been recorded using laser vibrometer technique. The main features of the force and displacement function have been found both in the time and frequency domain. It has been found that given method can be used for the detection of the potato tubers damage origin as well as for the differentiation among different varieties of the potatoes. There is also a chance to evaluate the main mechanical characteristics of the potato tubers by non - destructive way.
