| 中文摘要: |
| 通过跌落试验机对纸浆模塑平托盘进行对角线刚度试验，分析了其从不同高度跌落后的变形，校核了托盘的对角刚度，并利用数字图像相关方法对高速摄像机采集的图像进行了定量分析，得到了纸浆模塑材料的弹塑性力学特性，从而可以定量评定托盘抗冲击变形能力及对货物的承载能力。为纸浆模塑托盘的设计提供了重要指导。 |
| 英文摘要: |
| Drop tester was used for diagonal stiffness test of molded pulp pallet. The deformations of specimens in different drop height situations were analyzed to verify the diagonal stiffness. Digital images were obtained by high speed charge-coupled device (CCD) camera, and quantitative analysis the molded pulp pallet was carried out by using digital image correlation (DIC) method. Elastic-plastic mechanical characteristics of the molded pulp pallet was obtained, which was used for quantitative evaluation impact deformation resistance and carrying capacity of pallet. The purpose was to provide guidance for design of molded pulp pallet. |
