基于ABAQUS的液态奶缓冲包装优化设计

Optimal Design of Liquid Milk Buffer Packaging Based on ABAQUS

目前我国液态奶礼盒的缓冲包装主要采用瓦楞纸板,但其缓冲性能不能满足产品的运输要求。针对上述问题,以某乳制品企业生产的液态奶礼盒的缓冲包装为研究对象,利用Solid Works绘制包装件的三维立体图,并使用Hypermesh联合ABAQUS软件建立液态奶礼盒的有限元模型,并进行仿真跌落试验;通过分析上衬垫从800 mm处跌落的受力云图和变形云图,找出原有上衬垫的薄弱部位;针对上衬垫的薄弱部位,设计了两种新型的上衬垫,利用Auto CAD和Solid Works绘制出相应的平面图和三维立体图并进行仿真分析。试验结果表明:两种优化方案的牢固程度均高于原结构,且能满足产品运输要求。

At present, corrugated cardboard is mainly used in cushioning packaging for liquid milk gift boxes in China, but its cushioning performance could not meet the transport requirements. In order to solve this problem, a liquid milk cushioning package manufactured by a dairy enterprise was taken as the research object. SolidWorks was used to draw the 3D stereogram of the package. The finite element model of the liquid milk gift box was established by using Hypermesh and ABAQUS software, and the drop test was carried out. By analyzing the force and deformation nephogram of the upper liner falling from 800 mm, the weak part of the original upper liner was found out. Two new types of upper liner were designed for the weak part of the upper liner, and the corresponding plane and three-dimensional drawings were drawn by using AutoCAD and SolidWorks, and the test was carried out. The test results showed that the firmness of the two optimization schemes was higher than that of the original structure and could meet the requirements of product transportation.
