全瓦楞纸板的红酒包装内衬设计及跌落分析

目的为了更加便捷地运输和包装红酒等易碎玻璃制品,赋予其运输安全性、销售展示的美观性和一体性的功能。方法以750 mL溜肩红酒瓶为例,选择A型和B型瓦楞纸板,利用瓦楞纸板的挺度和折叠性对内衬结构进行造型设计,从而实现内衬结构的一板折叠成型。对红酒运输包装件进行跌落试验,得到红酒瓶的最大加速度曲线,然后利用Pro/E软件建立实体模型,导入有限元软件ABAQUS进行跌落仿真,得到包装件响应加速度曲线。结果 z方向最大加速度为215.33 m/s~2,比水平方向的冲击加速度低很多,即z方向跌落冲击缓冲性能好于水平方向。与跌落试验结果相比,误差均在可接受的范围内,表明有限元模型的建立是合理的,能够较好地反映所设计的红酒包装件在跌落过程中的动态缓冲特性。结论内衬结构全部采用环保的瓦楞纸板材料,易于加工成型。瓦楞纸板良好的缓冲性能和包装特性降低了红酒在运输过程中的破损率,这种全瓦楞纸板的内衬结构设计不仅克服了红酒传统运输包装的缺陷,而且弥补了纸质红酒包装结构单一的缺点,对产品最大响应加速度的分析表明该结构设计能够满足红酒瓶直立放置时的冲击防护要求。

Design and Dropping Analysis of Package Lining for Red Wine with All Corrugated Board

The work aims to more conveniently transport and package red wine and other fragile glassware and provide them with some functions like transport safety, beauty and integration of sales and exhibition. Taking 750ml sloping-shoulder red wine bottle as an example, the modeling of lining structure was designed by selecting type A and type B corrugated boards based on its stiffness and folding performance, thus achieving the lining structure by folding one-piece corrugated board. In addition, maximum acceleration curve of red wine bottle was obtained based on dropping test of transport packages of red wine; then solid model was established by using Pro/E software and imported into the finite element software ABAQUS for drop simulation; finally, the response acceleration curve of packages was obtained. The maximum acceleration in the Z direction was 215.33 m/s2, much lower than the impact acceleration in the horizontal direction, namely, its cushioning performance of drop impact was better than that in the horizontal direction. Moreover, compared with the results of drop test, the errors within the acceptable limits indicated that the finite element model built was reasonable and this model could better reflect the dynamic cushioning property of the red wine packages in the process of dropping. Such lining structure is entirely made of environmentally friendly corrugated boards easy to be processed and formed. And the breakage rate of red wine in the transport process is reduced because of the good cushioning properties and packaging characteristics of corrugated boards. Due to the design of lining structure with all corrugated boards, the defects of the traditional transport package of the red wine are overcome, and the deficiency of single structure of the paper package for red wine is also made up. Moreover, the analysis on the maximum response acceleration shows that such structural design can meet the requirements of impact protection when a red wine bottle is placed upright.
