Mechanical Characteristics and Microstructure of Cucumber Vine Straw
摘要
Abstract
In order to find the internal factors of efficient cutting and grinding process of the gardening straw , mechanical properties and the microstructure of the cucumber vine straw were tested in the laboratory .Results showed that root of cumber vine presented characteristics of plastic material , while middle and head showed the characteristics of brittle ma-terial.Average elastic modulus of cucumber vine stalk root is 280.58MPa, which is much greater than the middle and head with average elastic modulus of 198 .81 and 137 .22 MPa respectively .Further , cucumber vine straw is composed of epidermis , mechanical tissue , vascular bundle , parenchyma and can be considered a kind of porous ,cribriform , uneven composite .Both of these conclusions can provide the basis of cutting machinery developing and cutting parameters selec -tion.关键词
