Method for measuring fruit failure caused by different mechanical loads

Abstract

There are different limit values of mechanical effects causing bruise or failure of fruits during the variety of processes: the allowable drop height (fruit harvesting), the static load of fruit column at storage bin, or maximal vibration acceleration while transporting. To reproduce each forces from manipulation, different measuring devices have to be employed. Using the DyMaTest instrument, we can analyze the failure mechanism of fruits producing various load-functions: constant, linear or cyclic waveforms. With a developed measuring method, we have the opportunity to determine the fruit's failure parameters, and compare the deformation graphs using different compressive loads.
