| description | Ramie is a perennial crop and is normally harvested three times a year. The mechanical and physical properties of ramie differ from each period due to the different growth climate and environment. Impact tests of the ramie stems of the second harvest were carried out to discover the distribution law of fracture energy and to design the mechanical peeling parameters of ramie harvest and store. Tests of ramie stalk impact fracture energy under different conditions of moisture content were carried out to investigate the biggest impact fracture energy, and the result can provide a theoretical basis and main technical parameters for the determination of time for harvesting, storage, stripping, and mechanism design for low energy consumption with high efficiency separation. The results stated that with a decrease in moisture content, the impact of the lower portion of the fracture toughness of Ramie stalk gradually becomes smaller. Therefore, the ramie stalk should have been harvested and stripped in time. |
