智能座便器包装件跌落仿真研究和优化

Optimization and Dropping Simulation Analysis of Intelligent Implement Packaging

对某品牌智能座便器缓冲包装进行Creo2.0建模,在ANSYS Workbench的显式动力学模块中进行跌落仿真分析,得到缓冲包装以及座便器的应力、变形、加速度等数据。验证缓冲部分起缓冲作用的最主要因素,并进行参数优化,减少EPE衬垫的厚度。结果表明:缓冲部分瓦楞纸板的厚度、EPE衬垫的厚度和密度中起缓冲作用的最主要因素是缓冲材料的厚度。对智能座便器包装件进行结构优化,将EPE衬垫的厚度减小1 mm。为智能座便器运输包装结构强度理论的探讨和结构的优化设计提供了指导。

The model of an intelligent implement cushion packaging was set up in Creo 2.0. ANSYS Workbench was applied to carrying out droping simulation test for intelligent implement. The stress and strain distribution were acquired when the package of intelligent implement dropped vertically. The simulation experiment shows that the thickness of cushion material is the most important factor among the thickness of corrugated board and the thickness and density of EPE. The thickness of EPE liner was reduced 1 mm by optimization. This work may provide a scientific theoretical guidance for the product packaging design.
