Determination of Some Impact Parameters of the Olive Olea europaea L.cv. Memecik

Impact parameters make an important role in harvesting and handling of biological materials. In this research, impact parameters of the olive such as impact force, impact acceleration, impact energy, momentum and impact duration was evaluated depending on drop height and mass of the olive. Impact parameters were determined by using impact testing apparatus whose drop height and impact surface was changeable. Before the impact experiments, the olives were divided into five groups and then every groups of the olives were dropped from different drop heights varying between 0.4 and 2 m onto two different impact surfaces. Other impact parameters were calculated by using measured impact force values. The analysis of variance showed that the drop height has a signifıcant effect on the impact force, impact acceleration and impact duration of the olives. As a result of the study, for each group the olives, as the drop height increases, the impact force, impact acceleration, impact energy and momentum increase , but the impact duration decreases. Furthermore, the data on impact parameters versus the drop height are illustrated together with the confidence intervals of 95 %.
