| Abstract: | The variation of the vibration characteristics of a Huanghua pear was investigated using finite element simulations. A new
image processing technique was used to obtain the unsymmetrical and un-spherical geometrical model of a pear. The vibration
characteristics of this type of pear with the correlation of its behavior with geometrical configurations and material characteristics
were investigated using numerical modal analysis. The results showed that the eigenfrequency increased with the increasing
pear Young’s modulus, while decreased with increasing pear density, and decreased with increasing pear volume. The results
of this study provided foundation for further investigations of the physical characteristics of fruits and vegetables by using
finite element simulations.
