Experimental Investigation into Honeycomb Paperboard Vibration Transmissibility Property and Nonlinear Parameters Identification

Abstract

Abstract The vibration transmissibility property of honeycomb paperboard is investigated by experiments, the experimental results indicate that both the resonance frequency and resonance peak are sensitive to the altitude of excitation force. We can assume that both the damping and stiffness properties are nonlinear, and they can be expressed as the combination of the linear part with the cubic nonlinear part. An experimental system are formulated to record the experimental data, a system parameter identification procedure is presented base on harmonic balance method and total least square method. The system parameters under different static load and different excitation force amplitude conditions are identified and presented in this paper, the system model along with the identified can be used to simulate Tr-f curves, the comparison between the simulated curves with experimental data indicates the model is accurate to predict the vibration transmissibility property, which is important for proper use of honeycomb paperboard and anti-vibration packaging design.
