| 中文摘要: |
| 目的 对不同预压程度下多层钙塑瓦楞纸板隔振特性进行研究。方法 通过对不同预压程度下的钙塑瓦楞纸板进行振动试验， 发现压缩率为50%的钙塑瓦楞纸板有很好的隔振效果。然后基于材料的粘弹性理论建立压缩率为50%钙塑瓦楞纸板的本构模型， 并用最小二乘法识别参数， 根据车辆运输包装系统建立基于1/4车辆运输模型条件下的含易损件的二自由度非线性产品包装系统模型， 得到动力学方程并数值求解， 并通过一个算例说明该模型可直接用于包装隔振设计。结果 无量纲加速度值一般随着隔振材料面积的增大而减小， 随着材料层数的增加呈现先增大后减小的变化。结论 为进一步研究钙塑瓦楞纸板的隔振性以及相关包装设计提供一定的理论基础。 |

| The aim of this work was to study the vibration isolation characteristics of multi-layer calcium plastic corrugated board with different levels of pre-compression. Through a series of vibration tests with calcium plastic corrugated plate under different levels of pre-compression, we found that calcium plastic compressed corrugated board with 50% pre-compression ratio had good vibration isolation effect. The nonlinear dynamics constitutive relation of preloading calcium plastic corrugated plate was then established based on the cushioning viscoelastic theory. A nonlinear packaging system model with two degrees of freedom under 1/4 vehicle transport model was established based on vehicle transport packaging system using least squares identification parameters, and then dynamic equation as well as the corresponding results were obtained. The feasibility of the model in packaging vibration isolation design was illustrated through a numerical example. The study found that the dimensionless acceleration value generally increased as the area of vibration isolation material was reduced and first increased and then decreased with the increase of the number of layers. This study can provide theoretical basis for the vibration isolation performance of calcium plastic corrugated board and the related packaging design. |
