| 摘 要： | 通过正弦振动试验,研究了蜂窝纸板缓冲包装系统的振动特性,获得了蜂窝纸板的振动传递率曲线。采用MATLAB软件,利用最小二乘法对振动传递函数中的fn和c进行辨识,得到了理论传递率函数,并与试验数值进行了对比分析,证明了运用MATLAB和最小二乘法识别蜂窝纸板系统参数是可行的,具有较高的精度。利用识别出的固有频率和阻尼系数,对不同尺寸的蜂窝纸板进行了预测,预测结果与试验结果比较接近。

| Abstract: | 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. |
