KMT 动应变测量系统在水果定向中的应用
KMT Dynamic Strain Measurement System Application in Fruit Orientation
摘要
Abstract
The directed crux of the problem for fruit conveying process is to find the principal factors that affect orienta -tion success percentage , and contrast each factor by science combination , find the best combination to improve the orien-tation success rate of fruit in the actual production process .Using the method of combining orthogonal test and KMT dy-namic strain measurement system to determine the relevant factors of orientation .The value of KMT dynamic strain test retaining piece is consistent with calculated analysis of the data .And determining the main factors that influence the ori-entation of the fruit conveyor are as follows: the width of the entrance channel、the size of the speed of the clamping band、the apricots short diameter size .By orthogonal test ,gaining a group of optimum combination of experimental factors:the D is 25mm, the V is 13.2m· min-1, and the I is from 34mm to 35mm, In the case of this experiment , the apri-cots of directional success rate is greatly improved .By high-speed camera observation statistics , we found that:fruit di-rectional stability mainly concentrated on the fourth region in the orientation channel .Considering the impact of the grip-ping piece on the conveyor belt vibration , statistics out of apricot directional stability of the region focused on the fourth area of conveying channel ,and therefore to subsequent apricot segmentation of cutter location selection provides the theo -ry support .关键词
