Test of Mechanical Parameters for Litchi and Analysis for Its Difference
Abstract
In order to provide the basic mechanical data for the mechanical model and designing of machine for litchi, the compression experiments for the whole litchi fruit and its stone were conducted, while the tensile tests were carried out for the hulls of fresh litchi. The rupture force, stiffness and elastic modulus for the cultivar Feizixiao was obtained, and the elastic modulus for the hulls was also got. The results of tests showed that the rupture force, stiffness and elastic modulus of the whole litchi fruit’s vertical direction were stronger than horizontal direction, while the stone was opposite. Finally, for the elastic modulus of the litchi’s hulls, the horizontal direction was stronger than the vertical direction. The mechanical parameters of the litchi were different in different directions.
