Abstract:In order tO design the reasonable vibrating implements for harvesting fruits or nuts， the connection force of fruits and their stalk are measured，the experiments of stimulation and dislodging of fruits by vibration on the branches are carried out．The vibrating experiment on the branches of living tree are done outdoors．At last，the most suitable stimulation frequency，acceleration of vibration，time of vibration were obtained by the analyses of data．The useful technological parameter is offered to the design of implements for shaking the branches of orchard trees todislodge fruits or nuts．
