摘　　要：为提高缓冲包装设计的科学性、高效性,建立聚乙烯发泡棉(EPE)缓冲包装的设计流程及方法。依据《包装用缓冲材料动态压缩试验方法》(GB/T 8167-2008)对缓冲材料EPE的动态压缩性能进行试验,获取在不同冲击载荷条件下EPE的最大加速度-静应力曲线;结合产品的防护需求,确定缓冲包装的设计参数;对缓冲包装进行不同高度、落地方向的自由跌落试验,以检验缓冲包装对产品的防护效果,并结合对包装的其他评估指标,获得符合企业预期的最佳缓冲包装。以铁路信号继电器的缓冲包装设计为例,验证EPE缓冲包装设计流程及方法的可行性,提高设计效率和质量,为EPE缓冲包装的设计提供数据支持。In order to improve the scientifi city and effi ciency of cushion packaging design,the design process and method of EPE cushion packaging have been established.The dynamic compression performance of the cushioning material EPE is tested according to GB/T 8167-2008 Testing Method of Dynamic Compression for Packaging Cushioning Materials,and the maximum acceleration-static stress curve of EPE under diff erent impact load conditions is obtained.The design parameters of the cushioning packaging are determined according to the protection requirements of the product.The free drop test at diff erent heights and landing directions is carried out for the cushion packaging to test the protective eff ect of the cushioning package on the product,and obtain the best cushion packaging combining with other evaluation indicators of packaging that meets the expectations of the company.Taking the cushion packaging design of railway signal relay as an example,the feasibility of the design process and method of EPE cushion packaging is verifi ed,the design effi ciency and quality is improved,and the data support for the design of EPE cushion packaging is provided.
