| Abstract: |
| Vibration simulation experiments were carried out to obtain the peak value data of the vibration transmission characteristic curves of honeycomb paperboard in this study. Relationships between the four variables （i.e.， honeycomb paperboard aperture， contact area between weights and honeycomb paperboard， paperboard thickness， and weight of weights） and the frequency and corresponding vibration transmission rate were studied. Correlations of variable-frequency and variable-vibration transmission rate were obtained by polynomial fitting and the prediction accuracy of the two correlations was evaluated. The results showed that R2 for fitting accuracy of the two correlations were 0.997 and 0.991， respectively； R2 for prediction accuracy were 0.996 and 0.969， respectively； indicating that the accuracies of fitting and prediction were relatively high. By comparing the fitting results of 11 optimization algorithms， the Mcquard method+general global optimization method was determined to have the highest fitting accuracy. The method proposed in this study could effectively predict the key data of the vibration transmission rate-frequency curve within the set parameter range under certain environmental conditions， and reduce experimental workloads in practical operations. |
