A simulation of olive-tree harvesting model was constructed using measured tree's physical properties. It has been found that top parts of olive-tree respond to higher frequency "22Hz, and displacement of 10cm", while bottom portion was not harvested easily and responded to relatively lower frequency "14Hz, and displacement of 15cm". Therefore, it is concluded that the harvester must be designed to apply various frequencies with the ability of changing shaking amplitudes. Simulation was verified using different harvesting cases. According to simulated harvesting model, it was found that bottom portion of olive-tree did not react as other tree parts and has less efficient fruit removal. In addition, other results indicated that shaking point at 40cm above ground is effective in exiting most of the tree branches and could enhance harvesting process. tree, Harvesting, Finite element.
