摘要
目的研究JG3军用合成制动液在不同厚度瓦楞纸箱运输包装情况下,角跌落过程对包装箱内部制动液吹塑桶小包装应力、应变的影响。方法利用ANSYS/LS-DYNA软件,对不同厚度瓦楞纸箱运输包装的JG3军用合成制动液进行角跌落仿真实验,获取内部制动液吹塑桶小包装的有效应力及塑性应变数据,分析不同运输包装条件下制动液吹塑桶小包装的应力、应变特点。结果随着瓦楞纸箱运输包装厚度的增大,相同角跌落条件下,包装箱内的制动液吹塑桶小包装总体应力、塑性应变变小;在最厚的瓦楞纸箱包装条件下,部分制动液吹塑桶小包装存在应力、塑性应变集中区域。结论瓦楞纸箱运输包装对内装物的保护作用并非瓦楞厚度越大越好。
The aim of this work was to study the effects of angle drop process on the stress and strain of JG3 Military Synthetic Brake Fluid small packages in the packaging box when using corrugated cartons with different thickness as transport package. ANSYS/LS-DYNA was applied to carry out angle drop simulation test for JG3 Military Synthetic Brake Fluid packaged using corrugated cartons with different thickness. The effective stress and plastic strain data of the brake fluid small packages in the packaging box were acquired, and the characteristics of stress and strain under different transport package conditions were analyzed. With the increasing thickness of the corrugated carton, under the same angle drop condition, the overall effective stress and plastic strain of the brake fluid small packages in the packaging box decreased. In the thickest corrugated cartons, there were effective stress and plastic strain focus areas for some brake fluid small packages. The protection of the corrugated cartons to the packaged interior part with no cushion materials was not linearly correlated with the thickness of the corrugated cartons.
