Aiming at the current status quo of low level of mechanized harvesting of olive fruits in China,a kind of ol-ive harvesting machine suitable for low mountain valley area is designed.The whole machine and the structure of key components are selected and designed and calculated,and the eccentric block,the core component of the vibration harvesting,is analyzed by finite element.The results show that under static load,the maximum displacement of the eccentric block is 1.7×10-5 mm,the maximum stress is 3.251 4 MPa,and the stress-strain of the eccentric block meets the design requirements;the sixth-order intrinsic frequency of the eccentric block obtained by finite element modal analysis is above 4 000 Hz,which is much larger than the intrinsic frequency of the olive tree and the vibra-tion frequency of the harvester during the working process,so the olive harvester will not cause resonance during the working process.Therefore,the olive harvester will not cause resonance damage to the machinery during the working process,and has good stability and safety.The study can provide a reference for the mechanization of olive harvesting.
