摘要
为探寻目前用于土木工程减隔震方面的基于唯象理论的Neo-Hookea模型、Mooney-Rivilin模型和Yeoh模型三种橡胶本构模型在有限元分析中的匹配程度,先对橡胶进行静力加载实验,然后通过实验数据处理得到三种本构模型各自的参数,并将三种模型参数分别代入到有限元软件进行分析计算,最后将得到的三种模型下的计算结果与实验数据对比.分析结果表明,在橡胶压缩时,Neo-Hookea模型适用于压应变为045%的范围,Mooney-Rivilin模型和Yeoh模型适用于压应变为≥60%的范围.研究对橡胶压缩时如何选择本构模型做出了解答,过程中所采用的研究方法和研究结果也有一定的借鉴意义和实用价值.
To study the matching degree of Neo-Hookea model,Mooney-Rivilin model and Yeoh model,which are based on phenomenological theory and used in seismic mitigation and absorption,in finite element analysis,the static loading test on rubber were done,then the respective parameters of each constitutive model were got by processing the experimental data,and the parameters of the three models were substituted into the finite element analysis software to analysis and calculate.The results show that,when the rubber is compressed,Neo-Hookea model is suitable for a range of 045% of compressive strain,and the Mooney-Rivilin model and Yeoh model is suitable for compressive strain of more than 60%.This research explained the choosing of constitutive model for rubber compression,and the research methods and results used in the process also has a certain significance and practical value.
