【摘要】 果品损伤已成为制约我国农业经济发展的重要因素之一,跌落作为引起果品损伤的一个主要原因应予以控制。考虑到果品在采摘等环节主要发生单果跌落,而运输过程中常堆积多层形成果品包装系统多果跌落也较常见。文中采用Kuwabara-Kono模型描述果品粘弹性,建立了单、多层果品系统动力学模型并在此基础上采用理论的方法得到单、多层果品系统跌落破损边界曲线。结果表明:果品最大允许损伤率、堆码层数、跌落高度、果品粘弹性特征参数等对果品系统跌落破损边界影响显著。研究结论对果品损伤判别及其减损工艺与包装设计具有重要价值。更多还原

【Abstract】 Fruits damage has become one of the major factors restricting the development of modern agriculture. Drop,as one of the main reasons for fruits damage,should be controlled.Considering both the drop of single-layer fruit and multi-layer fruit are common,in this paper the mechanical model of single and multi-layer fruit was developed based on the Kuwabara-Kono assumption.And then the dropping damage boundaries were got by a theoretical method.It’s shown that the effect of maximum allowable bruising ratio,numbers of stacking layers, dropping height,and viscoelastic parameters of fruits on the dropping damage boundary is noticeable.The results have very important value in controlling fruits damage.更多还原
