电饭煲运输包装设计及跌落仿真分析

为研究电饭煲在流通过程中运输包装的缓冲性能，选择了环保型的缓冲材料发泡聚乙烯（EPE） 为缓冲衬垫、AB型瓦楞纸板为外包装箱进行缓冲包装设计。根据电饭煲的规格和缓冲要求，对缓冲衬垫 和外包装箱的结构进行了计算和设计，并利用Solidworks软件进行建模，并将其导入ANSYS中，设置各层 缓冲包装材料的参数后，进行了自由落体跌落仿真试验；通过分析电饭煲运输包装件与地面接触瞬间的 应力分布云图和最大应力曲线，发现在跌落过程中的最大应力出现在外包装箱与地面接触位置，最大应 力小于电饭煲材料ABS的极限应力。因此，所设计的运输包装满足产品的缓冲要求，达到了保护电饭煲的 目的。

Design of Transportation Packaging for Electric Cooker and Simulation Analysis of Drop

In order to study the cushioning performance of electric rice cooker in the process of circulation, the transportation packaging was designed by choosing the environmental friendly cushioning material foamed polyethylene (EPE) as the buffering cushion, and AB type corrugated board as the outer packaging. According to the specification and cushioning requirement of the rice cooker, the structures of cushioning lining and outer packing box were calculated and designed, and were modeled by Solidworks software. The established model was input into ANSYS, with the parameters of each layer of cushioning packaging material set up, and the free falling body drop simulation test was carried out. By analyzing the stress distribution cloud diagram and the maximum stress curve at the moment of the contact with the ground, it was found that the maximum stress occurred in the position of the outer packing box contacting the ground during the fall process, and the maximum stress was smaller than the ultimate stress of the rice cooker material ABS. Therefore, the designed transportation packaging could meet the buffering requirements and achieve the purpose of protecting the rice cooker.
