| 目的 研究0945型瓦楞纸板衬垫三角形支座底部支撑点位置对其缓冲防振性能的影响。方法 以0945型衬垫三角形支座的底部支撑点与边缘的水平距离为结构参数，采用B楞瓦楞纸板制作5种0945型衬垫试样，利用静、动态压缩试验、随机振动试验分析衬垫的缓冲防振性能。结果 应力-应变曲线表明，当底部支撑点与边缘的距离为40 mm时，衬垫的最大应力达到78 kN；当该距离为0时，衬垫的单位体积应变能达到35.67 kJ/m3。最大加速度-静应力曲线表明，40 mm时衬垫的最大加速度最小。随机振动功率谱密度曲线表明，距离为0时，衬垫的功率谱密度峰值最小。结论 0945型瓦楞纸板衬垫三角形支座为直角三角形时，垂直边能承受较大载荷，产生较小变形，不易塌陷，缓冲防振性能最好。 |

| The work aims to research the impact of bottom supporting point of triangular support on the cushioning and anti-vibration properties of 0945-type corrugated paperboard liner. With the horizontal distance between the bottom supporting point of the 0945-type liner's triangular support and the edge as structural parameter, and then five kinds of 0945-type liner samples were made by B-flute corrugated paperboard. Through the static and dynamic compression tests and random vibration test, the cushioning and anti-vibration properties of the liner were analyzed. The stress-strain curves showed that the maximum stress of liner reached up to 78 kN when the distance between the bottom supporting point and the edge was 40 mm. The unit volume strain energy of the liner was 35.67 kJ/m3 when such distance was 0 mm. The maximum acceleration-static stress curve showed that the maximum acceleration of the liner was the minimum when the distance was 40 mm. Power spectral density curve of random vibration showed that the peak of power spectral density was the minimum when the distance was 0 mm. When the triangular support of 0945-type corrugated paperboard liner is right triangular, the perpendicular edge can endure larger loads and produce smaller deformation and not be easy to collapse, and the cushioning and anti-vibration properties are the best. |
