摘　　要：目的对纸浆模制波状结构形式的缓冲填充物进行结构设计与缓冲包装性能的测试。方法设计并加工制备2种纸浆模制品波状缓冲结构填充物,其中A组试样的高度均为30 mm,波状角度分别为5°,15°,30°;B组试样确定的波状角度均为5°,高度变化分别为10,20,30 mm。对2组试样分别进行了静态压缩、动态冲击和振动试验。结果高为30 mm,波状角度为5°,15°,30°的波状结构最大静载荷分别为1230,1430,1600 N,波状角度为5°,高为20和30 mm的波状结构最大静载荷分别为560,1380 N。结论静态压缩试验表明高度一定时,纸浆模制缓冲结构的波状角度越大,载荷能力越强,波状角度一定时,高度越高,载荷能力越强;动态冲击试验表明纸浆模制缓冲结构的波状角度、高度影响着结构体的缓冲应用范围;振动试验表明在给定的载荷条件下试样避开了公路运输的共振频率。This work aimed to design the structure of molded pulp with bi-wave cushioning and test the cushioning performance. Two different groups of the cushioning samples were designed, processed and prepared, group A with same the height of 30 mm and varying wave angles of 5°, 15° and 30°, respectively, while group B with the same wave angle of 5° and varying heights of 10, 20 and 30 mm, respectively. The performance was tested by static compression, dynamic impact and vibration tests. The maximum loads of group A samples with 30 mm height and 5°, 15° and 30°, were 1230, 1430 and 1600 N, respectively, while those of group B samples with 5° and 20, 30 mm height were 560 and 1380 N, respectively. The maximum loads became lager with increasing wave angle at constant height, and with increasing height at constant wave angle. The dynamic impact test showed that the height and wave angle impacted the cushioning application scope of the structure, and the result of vibration test proved that the profiled structure molded pulp could completely be used for highway transportation.
