实验室测试表明，巴特利特梨的托盘纤维板箱在低于 40 Hz（周期/秒）的振动频率下最容易受到擦伤损坏，这在冷藏公路拖车中很常见。损害研究表明，在运输过程中观察到的四个频率区域（3.5 Hz、9 Hz、18.5 Hz 和 25 Hz）中，巴特利特梨在 3.5 Hz 和 18.5 Hz 处受损最严重。实验室研究还表明，梨的纤维板箱会在低于 40 Hz 的频率下放大振动，因此，对于某些频率，托盘中顶部盒子的盖子的加速度是底部盒子输入水平的三到四倍。
Laboratory tests revealed that palletized fiberboard boxes of Bartlett pears are most susceptible to bruising damage at vibrational frequencies below 40 Hz (cycles/s), which are common in refrigerated highway trailers. Damage studies indicate that of the four frequency regions observed in-transit (3.5 Hz, 9 Hz, 18.5 Hz, and 25 Hz), Bartlett pears are most severely damaged at 3.5 Hz and 18.5 Hz. Laboratory studies also show that fiberboard boxes of pears amplify vibration at frequencies below 40 Hz such that, for some frequencies, the lid of the top box in a pallet is accelerated three to four times more than the level input to the bottom box.
