研究了杏果实在振动采收过程的运动规律、果实振动脱落时的速度变化规律。运用果树振动装置进行了杏果实振动采收试验,借助高速摄像仪对振动采收过程进行了跟踪拍摄,通过 Phantom 软件对图像进行捕捉、跟踪、分析和计算。结果发现:杏果实完全脱落前6~10 ms时刻,由于惯性力的作用使得果柄沿径向出现裂痕,表现出脱落的迹象;杏果实与枝干的相对瞬时速度出现峰值,果柄横截面出现裂纹,发生断裂。应用高速摄像技术对振动落果时的速度进行研究,可以较好地反映落果的运动规律,直观地了解整个落果过程。
研究瞭杏果實在振動採收過程的運動規律、果實振動脫落時的速度變化規律。運用果樹振動裝置進行瞭杏果實振動採收試驗,藉助高速攝像儀對振動採收過程進行瞭跟蹤拍攝,通過 Phantom 軟件對圖像進行捕捉、跟蹤、分析和計算。結果髮現:杏果實完全脫落前6~10 ms時刻,由于慣性力的作用使得果柄沿徑嚮齣現裂痕,錶現齣脫落的跡象;杏果實與枝榦的相對瞬時速度齣現峰值,果柄橫截麵齣現裂紋,髮生斷裂。應用高速攝像技術對振動落果時的速度進行研究,可以較好地反映落果的運動規律,直觀地瞭解整箇落果過程。

In order to study the apricot fruit in the motion law of vibration harvesting process and the rule of changed ve -locity when the fruits are divorced by shake .we use the fruit trees vibration device for apricot fruit harvest vibration test . We also have the high-speed camera to follow vibration harvest process .Through the Phantom software of image capture , track, analysis and calculation .Before 6~10 ms moment apricot separate completely , we found the peduncle along the radial fractures because of the effect of inertia force , showed signs of falling off .Apricot fruits and branches of relative in-stantaneous velocity have the peak .Peduncle of cross section has crack and fractures .Researching the velocity of the fruit falling off in vibrations by using high-speed video camera technology , we can better reflect the law of kinematics and intuitively understand the whole process of the fruit falling off .
