研究枝干和杏果实在落果过程中的瞬时速度及位移变化规律，为振动机械化采收提供必要的理论依据。通过机械振动装置对杏树进行振动采收试验，借助高速摄像仪对振动采收过程进行跟踪拍摄记录，利用 Phantom软件对图像进行分析、计算。由分析可知：在受迫振动中同枝干、不同位置的杏果实瞬时速度的变化规律有6个阶段，所在枝干的瞬时速度峰值出现时刻都较杏果实瞬时速度峰值出现的早；杏果实瞬时速度的变化周期与所在枝干瞬时速度的周期变化相近，约为70～80ms，完全分离前的6～10ms，杏果实与所在枝干的相对瞬时速度达到最大。结果证明：振动采收时使用高速摄像装置进行速度分析，可以较好地得到落果的运动规律，直观地了解整个落果过程并且量化杏果实的力学性能参数。

In order to research the instantaneous velocity and displacement variation of branches and apricot fruit in the fruit dropping for vibration to provide the necessary theoretical basis in mechanical harvesting .By mechanical vibration device for doing apricot harvest vibration test , using high-speed camera for tracking and recording vibration harvesting process , and using Phantom for analyzing and calculate .By forced vibration analysis shows that the instantaneous velocity of apricot fruit have six stages at the different variation positions in the same branches ,where the branches of the instanta-neous velocity peak moments are more earlier than the instantaneous velocity peak moments of apricot fruit ,the changing cycle of instantaneous velocity of apricot fruit instantaneous speed are similar to the branches ,about 70ms to 80ms.Be-fore 6-10 ms completely separated ,the relative instantaneous velocity of apricot fruit and the branches is maximized .The results prove that the use of high-speed analyzing the velocity in the vibration harvesting , you can get better the move-ment and intuitively understand the whole process of fruit dropping ,and quantify the mechanical properties of apricot fruit parameters .
