| 中文摘要 | 介绍了获得聚氨酯泡沫塑料压缩状态下应力—应变关系的恒速加、卸载试验与参数识别的基本方法与过程。针对2种不同密度的聚氨酯泡沫塑料,以不同的速率做了恒速加、卸载试验,以遗传积分模型为例介绍了利用恒速加、卸载试验识别模型参数的方法,提出了进行试验数据预处理的线性插值法。; This paper presents a test procedure and method to identify thestress-strain relation of polyurethane foams under compression.Experiments are carried out on two foam blocks which are used for vehicle seat cushion.For each experiment,the foam cushion is loaded and unloaded at a constant speed.The stress-strain relation is formulated by combining a strain power series for nonlinear elasticity and inheritance integral for linear viscoelasticity.Based on the formulation,the approach for parameter identification is briefly introduced.One example is given to demonstrate the agreement between the model and the test data.; 国家自然科学基金(50675110) |
