| 中文摘要: |
| 为研究发泡聚乙烯的隔振性能，测试了质量块和振动台的加速度信号；运用最小二乘原理，消除了实验数据的趋势项；建立了发泡聚乙烯多项式动力学模型，识别出了一个工况下的衬垫的参数；运用Runge-Kutta法和重构恢复力-位移曲线，证明了模型的正确性；最后，运用相同的方法，得出了其它工况下的参数识别结果。研究的结果可直接为防震包装提供理论依据。 |
| 英文摘要: |
| Acceleration signals of mass and electrodynamics shaker were measured. Least-squares method was applied and the trend items of the signals generated by shaker were eliminated. The polynomial dynamic model of polyethylene was established. The stiffness and damping of a load condition was identified. Runge-Kutta method was applied to reconstruct force-displacement curve and the correctness of the model was proved. The parameters of other load conditions were obtained with the same method. The computed results can be references for vibration isolation packaging. |
