Viscoelastic Property of Honeycomb Paperboard and Dynamic Response Analysis
The creep experiment and the quasi-static are carried out to learn the properties of honeycomb paperboardroughly, the creep and hysteresis phenomena are important manifestations of honeycomb paperboardviscoelastic properties. In addition to the static and quasi-static effects, the viscoelastic property also influencesthe dynamic properties of honeycomb paperboard. A linear differential equation is adopted to accountfor the complexity of honeycomb paperboard dynamic properties. Base on the Laplace transform, themodel for the honeycomb paperboard properties is formulated. The relaxation kernel is used to account for theviscoelasticity, and it is expressed as the sum of complex exponentials. The free response of the mass loadedhoneycomb paperboard is analyzed based on the Laplace transform and substitution method, the free responseof the viscoelastic system have multiple vibration modals. The forced response of the mass loaded honeycombpaperboard to general force function is analyzed based on the state-space approach. The simulation resultsindicates the viscoelasticity can provide more stiffness and damping forces than the equivalent singledegree of freedom system.
