摘　　要：考虑到蜂窝纸板的组成成分,可将蜂窝纸板建模为具有粘弹性的线弹性材料,并在蜂窝纸板的动态特性模型中引入了松弛算子,推导出了蜂窝纸板参数识别的方法.对蜂窝纸板—质量系统进行冲击激励实验,根据实验数据进行参数识别.在支座激励的条件下,推导出了蜂窝纸板振动传递率公式,并将实验值和利用该公式的模拟值进行比较,结果表明,粘弹性是引起振动传递率多模态性的原因.The honeycomb paperboard can be modeled as linear material with viscoelastic property, considering the compositions. Relaxation kernel is used in the dynamic properties model of honeycomb paperboard, and the parameter identification procedure is presented. The honeycomb-mass is excited by shock hammer, and the system parameters are identified using the experiment data. The vibration transmissibility equation is given,then using this equation, the transmissibility-frequency curve is simulated along with the experiment result. The result shows that the viscoelastic property makes the vibration transmissibility curve have multiple resonance frequencies.
