中文摘要:
      目的 研究在不同压缩速率下纸瓦楞夹层板的压缩变形与塑性吸能特性。方法 利用Hoff夹层板、 正交各向异性弹性薄板理论和工程梁理论, 研究瓦楞夹层板的横向压缩位移, 分析瓦楞芯层的压缩变形模式及塑性吸能特性, 提出芯层结构的压溃强度模型, 并通过静态压缩实验进行对比分析。结果 B型、 C型纸瓦楞夹层板的压溃强度理论预测值分别为0.1195, 0.0612 MPa, 在1, 12, 18, 48 mm/min的压缩速率下, B型纸瓦楞夹层板的压溃强度分别为0.1011, 0.1071, 0.1048, 0.1075 MPa, C型纸瓦楞夹层板的压溃强度分别为0.0462, 0.0640, 0.0475, 0.0451 MPa。结论 低应变率(低压缩率)条件下, 纸瓦楞夹层板的横向压缩性能影响基本不变, 弹性强度、 屈服强度、 压溃强度等基本相同。对于相同的材质, 几何参数对纸瓦楞夹层板的压缩性能和塑性吸能影响较大。
英文摘要:
      Compressive deformation and plastic energy absorption property of paper corrugated sandwich panel were investigated at different compressive rates. Transverse compression displacement was studied based on Hoff's sandwich plate, orthotropic plate theory and engineering beam theory. Compression deformation mode and plastic energy absorption property of corrugated core were analyzed and compression strength model of corrugated core was presented and compared with the results of static compress experiments. Theoretical predictions of crushing strength of B and C paper corrugated sandwich plates were 0.1195 and 0.0612 MPa, respectively. The results of static compress experiments of B and C paper corrugated sandwich plates at compressive rates of 1, 12, 18, 48 mm/min were 0.1011 and 0.0462 MPa, 0.1071 and 0.0640 MPa, 0.1048 and 0.0475 MPa, 0.1075 MPa and 0.0451 MPa, respectively. There was negligible effect of low strain rates on the compressive properties of paper corrugated sandwich panel, and the elastic strength, yield strength and crushing strength also remained almost the same. For the same materials, section geometry of the panel had great effect on the compressive characteristics and energy absorption property of paper corrugated sandwich panel.
