用于四角固支的三角形瓦楞衬垫动态缓冲特性分析

Dynamic Cushioning Performance Analysis of Triangle Inserts Based on Four-corner Fixed Corrugation

提出一种四角固支瓦楞缓冲包装结构,研究其核心结构件三角形瓦楞缓冲衬垫的动态缓冲性能。对四角固支瓦楞缓冲结构形式进行简化,以主要的三角形支撑结构单元为研究对象,构建其缓冲结构试验模型,合理设计动态压缩试验,得到试样的最大加速度-静应力关系曲线。试验表明,用于四角固支的三角形瓦楞缓冲结构衬垫的动态缓冲性能和其厚度及周长尺寸(受力面积)有直接关系,对低负载产品包装可提供较好动态缓冲性能。通过选取高强度瓦楞原材料,或多个瓦楞衬垫组合可满足高负载产品包装的缓冲要求。研究得到的最大加速度-静应力曲线可为四角固支瓦楞缓冲系统设计提供理论依据。通过设计合理的三角形瓦楞缓冲厚度及周长尺寸,可实现减小包装整体尺寸,提高运输包装设计效率的目的。

A kind of four-corner fixed corrugation packaging structure is proposed,and the dynamic cushioning performance of the triangle cushion inserts is studied.The structure is simplified at first,and then focused on its main component,triangle corrugated inserts.A test model of the triangle supported four corner fixed corrugation cushion structure was constructed,the dynamic compression test was designed and tested,in order to get the corresponding cushion property curves of different specimen,Gm-σs curves.It shows the triangle insert has good dynamic cushion performance for light load products,by choosing high density corrugated material or multi-inserts can satisfy heavy load products.The research can provide theoretical basis to guide the design of the relevant cushion structure in packaging industry,reasonable perimeter design can effectively reduce the overall size of the cushion structure,meanwhile improve transport efficiency.
