摘要

摘要: 利用瓦楞纸板衬垫-砝码系统模拟真实的包装件。考虑了瓦楞纸板的粘弹性,对瓦楞纸板衬垫在冲击激励下的动态特性进行了建模。将系统自由响应数据表达为复指数函数叠加的形式,采用复指数法识别出自由响应数据的极点和留数。建立了瓦楞纸板衬垫冲击激励实验系统,识别出不同载荷条件下瓦楞纸板的模型参数。采用圆整冲击加速度函数模拟真实的半正弦波,分析了系统在冲击支座激励下的加速度响应。

Abstract: The corrugated paperboard cushion-mass system was used to simulate the real packaging. Dynamic proper-ties model of the corrugated paperboard excited by shock load was obtained with viscoelasticity of corrugated paper-board taken into account. The free response data were expressed as the sum of complex exponentials by Laplace anal-ysis,and the poles and residues of free response data were identified by Prony method. An experimental system wasset up to record the response of corrugated paperboard cushion-mass system to base shock excitation. The parametersof the model were identified under different load conditions. The rounded impulse function was used to simulate theshock excitation and the acceleration response of the corrugated paperboard cushion-mass system was deduced.
