Mechanical Properties of"Bali"Pineapple Peel under Different Loading Speeds
摘要
Abstract
The mechanical properties of pineapple peel puncture were studied in order to provide reference for fruit quali-ty evaluation,optimization and improvement of pineapple harvesting and processing equipment,and theoretical basis for reducing pineapple fruit damage.Taking"Bali"pineapple peel as the research object,the peel was divided into upper,middle and lower parts according to the growth law of pineapple.Five different loading speeds were used to test the punc-ture mechanical properties of different parts of pineapple,and the effects of different loading speeds,different puncturing parts and different puncture pressure head sections on the puncture strength of the peel were analyzed.The results showed that the puncture intensity in the middle of the peel was the lowest,and the puncture intensity in the lower part was the strongest.The indenter section and different puncture sites had a negative correlation with the peel puncture intensity(p＜0.01);the different puncture sites had a positive correlation with the peel puncture strength(p＜0.01).The effect of puncture intensity was significant(p＜0.01).From this,it was concluded that the peel puncture strength had a very sig-nificant correlation with the indenter section and the puncture site,and the loading speed had no correlation with the puncture strength.关键词
