对同一规格、不同开孔位置的某重型装饰灯具外包装瓦楞纸箱进行了抗压强度的试验,以探讨提手孔位置对纸箱抗压强度的影响。在瓦楞纸箱侧面中线上方H/6以内的高度进行四等分,得到实验的4个测试点,以此4点为中心开取弧型提手孔,分别对其进行空箱抗压强度测试。结果表明:纸箱侧面开孔后.纸箱的抗压强度会降低;当提手孔开孔位置处于箱面中线上方H/18高度时,抗压强度损失最小。
Abstract: Strength tests are conducted on the packaging corrugated boxes of heavy decorative lights with same size and different handle locations to discuss the effects of handle hole on the compressive strength. The height within 1/6 above the height of the lateral center line is evenly quartered and 4 test points are determined, based on which handle holes are opened and compressive strength tests of empty box are taken. The results show the compressive strength degrades if the box is punched on the lateral side, and the loss of strength is minimal when the handle hole is located at 1/18 of the height above the center line on the box.
