The vibration property of honeycomb paperboard was investigated by sine vibration tests, and the vibration transmissibility curves of honeycomb paperboard were obtained. Using MATLAB program, the natural frequency and damping coefficient of transmissibility function were identified based on least-square method. By comparing the fitting curves and actual curves, the model was verified to be correct and feasibility. Prediction of different area honeycomb paperboard was made and the results were closer with the practice.
