The vibration transmissibility properties of honeycomb fibreboard are investigated by experiments, and a model is presented to account for the vibration transmissibility of honeycomb fibreboard. An experiment system is formulated and the vibration transmissibility-frequency curves are obtained under different base excitation amplitude conditions. According to the transmissibility experiments data, it can be assumed that both the stiffness and damping properties are nonlinear. The hysteresis loops of the honeycomb fibreboard-mass system are experimentally obtained, and are used to investigate the stiffness and damping properties of the system. The honeycomb fibreboard's uni-directional vibration transmissibility behavior is modeled by using nonlinear stiffness, the combination of velocity proportional damping and quadratic type nonlinear damping components. The parameters in the model are identified by using one-term harmonic balance method,and the parameters under different load condition are presented. The model and the parameters in this paper can be used to simulate the transmissibility-frequency curves accurately. The model can be used to understand the vibration transmissibility behaviors of the honeycomb fibreboard, and the simulated transmissibility-frequency curves can be used in the packaging design.%以试验为基础,对蜂窝纸板的振动传递特性进行了建模.构建了蜂窝纸板振动传递特性试验系统,根据试验结果,蜂窝纸板在不同的支座激励作用下,其振动传递特性具有很大的不同,因此可认为蜂窝纸板的弹性和阻尼特性均具有非线性.通过调查在特定频率下,蜂窝纸板在不同幅值的支座激励下的迟滞特性,可将蜂窝纸板的弹性力建模为压缩量的奇次多项式,蜂窝纸板的阻尼可表示为粘性阻尼和速度平方阻尼的组合.采用谐波平衡法及最小二乘法,识别出不同载荷条件下蜂窝纸板振动传递特性模型中的参数,通过试验结果和模拟结果的对比,该模型能准确模拟蜂窝纸板的振动传递率曲线,这为蜂窝纸板在防振包装设计中的应用提供了理论基础和设计依据.
