| 摘要: |
| 目的 验证纸浆模塑缓冲衬垫是否具有缓冲性能，能否有效保护产品不受损伤。方法 基于吊灯灯罩与纸浆模塑衬垫之间的装配关系，以跌落冲击为环境载荷，采用Ansys/LS-DYNA软件进行高度为 1000 mm的跌落仿真分析，获取纸浆模塑缓冲衬垫应力-应变云图、加速度响应曲线等动态特征和相关参数，以此分析吊灯灯罩纸浆模塑衬垫在整个跌落过程中的作用。结果 纸浆模塑衬垫凸台发生了变形，作用力由纸浆模塑衬垫向灯罩扩散；整个模型重心点的加速度小于最低点的加速度；整个模型重心点和最低点速度与位移变化符合实际情况。结论 纸浆模塑缓冲衬垫通过结构的变形和破坏来吸收外界冲击能量，以及延长作用力时间起到缓冲作用，能在物流过程中对产品进行有效保护。 |

| Abstract: |
| The work aims to verify whether the molded pulp cushion pad has buffer performance and whether it can protect products from damage. Based on the assembling relationship between the chandelier lampshade and molded pulp cushion pad, by taking the drop impact as the environmental load, the simulation and analysis on dropping at the height of 1,000 mm were carried out by Ansys/LS-DYNA software. And dynamic characteristics, such as the stress-strain nephogram, acceleration response curve and so on, as well as the related parameters of the molded pulp cushion pad were obtained, based on which the role of chandelier lampshade' s molded pulp cushion pad in the whole dropping process was analyzed. The molded pulp cushion pad convex platform was subject to deformation and the force was diffused from the molded pulp cushion pad toward the lampshade. The acceleration of barycenter point was less than that of the lowest point of the entire model; the change in speed and displacement of the barycenter point and the lowest point of the entire model accorded with the actual situation. Molded pulp cushion pad absorbs external impact energy through the structural deformation and destruction, and extends the time of force application, so as to play a buffer role in effectively protecting the product in the logistics process. |
