EBE楞瓦楞纸板缓冲曲线研究

Cushion Curve Study of Corrugated Paperboard with EBE-flute

瓦楞纸板因其可降解性、优良的缓冲性能和隔温性能,常用于运输包装中。首先利用万能试验机得到了EBE楞瓦楞纸板静态应力-应变曲线,结果表明瓦楞纸板应力-应变曲线具有非单调性的特点,因此求解瓦楞纸板缓冲曲线需要分段处理。最后计算了EBE瓦楞纸板的缓冲系数-最大应力曲线,并给出了使用缓冲曲线设计包装结构的算例。

Corrugated paperboard is used for transporting packaging,as it has reasonable degradation,cushion and thermal insulation properties.The stress-strain curves was obtained by using universal testing machine.The result showed that the stress-strain curve is not monotonous,so it needs to process separately for calculating cushion curve.The cushion coefficient verses maximum curve was calculated,and the example was given to guide the structure design of packaging.
