Driving Point Mechanical Impedance of Blueberries

ABSTRACT BASED upon data obtained from 170 berries, a six element mechanical model was proposed and model parameter estimates were determined for each berry. Ex-cellent agreement was obtained between impedance model berry mass and measured berry mass (r = 0.928) while resonable agreement was obtained between model spring constants and measured qu^si-static berry firm-ness (r = 0.761).
