Researching the Movement of Fruit Dropping Based on High-speed Camera
摘要
Abstract
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 .关键词
