聚苯乙烯泡沫衬垫的缓冲性能研究及建模

RESEARCH ON BUFFER PROPERTIES ABOUT POLYSTRENE FOAM LINER AND THE ESTABLISHMENT OF MODEL

通过动态和静态压缩试验，分析了聚苯乙烯泡沫塑料衬垫缓冲性能的基本特征，并应用弹塑性理论，建立了既能反映静态应力应变规律又能反映其恰证的非线非线性数学模型，同时根据试验数据识别了模型参数．

This paper analyses the basic characteristics of buffer properties of polystyrene foam liner bymeans of dynamic and static tests. Based on elastoplastic theory, nonlinear mathemacal model was established.This model can reflect not only the static law between stress and strain, but also the basic chacracteristic of the bufferproperties of the foam. The model parameters were identified according to test data.
