目的 分析 ISO 8611—2011 检测技术,研究木托盘垫块和底铺板尺寸的变化对木托盘性能的影响。 方法 基于 ISO 8611—2011 对 2 种垫块和底铺板尺寸不同的木制平托盘进行气囊弯曲试验、垫块冲击试验和底铺板冲击试验。 结果 托盘气囊弯曲试验中的平均变形量分别为 8 . 36 mm 和9 . 05mm,极限载荷平均值分别为 4840 . 4 kg 和 4739 . 8 kg,垫块冲击试验中的平均冲击次数分别为 2 . 9 次和 9 . 3 次,底铺板冲击试验中的平均冲击次数为 5 . 2 次和 4 . 5 次。 结论 在托盘垫块受到冲击时,其抗冲击能力受中间垫块的尺寸和垫块与铺板连接的钉子数量及钉子排列方式的影响较大。

Objective To analyze ISO 8611—2011 detection technology, and study the influence of the dimension of block and bottom deck on the performance of the wood pallet. Methods Air-bag bending test, block impact test and bottom deck impact test were performed for the test pallets with different dimensions of pallets block and bottom deck based on ISO 8611—2011. Results In the air-bag bending test, the average deformations were 8. 36 mm and 9. 05 mm, respectively, and the average ultimate loads were 4840. 4 kg and 4739. 8 kg, respectively. In the block impact test, the average impact times were 2. 9 and 9. 3, respectively. In the bottom deck impact test, the average impact times were 5. 2 and 4. 5, respectively. Conclusion The experiments indicated that the middle block dimensions and the number of nails connecting the block with the deck and the nail arrangement had strong influences on the impact resistance of the pallet when the block was impacted.
