- W2349164102 abstract "The mechanical properties of fruit and vegetable are important in design of harvesting, sorting and processing system. Indexes of judging the mechanical properties of fruit and vegetable are modulus of elasticity, failure stress, failure strain, failure energy, delayed energy and degree of elasticity, however, the mechanical properties have concerned with loading rate of experiment. In this paper, the effect of the loading speed rate on mechanical properties was studied by applying uniaxial compression to radish, and the theoretical basis was improved for design of and secure conveyance process device.0 前言 果蔬在收获、加工、贮藏、包装及运输和销售等过程中都容易因过大的静载、碰撞及振动等引起各种机械损伤,而这些机械损伤是构成果蔬采后损耗的主要因素之一。据估计在高度机械化的国家由此引起的平均损耗约占总产量的30%～40%,从而带来巨大的经济损失,因此减少果蔬的力学损伤,是全世界农产品业广泛关注的问题[1～2]。要解决此问题,必须深入了解果蔬的力学特性,将其在收获加工及产品分级等的变形控制在弹性范围内,为有关加工机械及工艺的设计提供理论依据。 萝卜是东北地区的常见蔬菜,营养价值很高,但其在实际运输及加工中将受到各种载荷的作用。加载速度可分为静态加载、准静态加载、快速加载及撞击加载等,加载方式的不同,物料的力—变形关系、各力学指标等都会有所不同。本文就加载速度对萝卜力学特性的影响进行了试验研究,为有关设计和生产部门提供一些基础依据。" @default.
