摘要

利用软钢的Ramberg-Osgood本构关系(R-O模型),依据经典力学原理推导建立了X形和三角形钢板阻尼器的阻尼力滞回模型。首先,给出了循环加载下软钢材料的应力-应变R-O本构关系;其次,推导建立了基于R-O本构关系的钢板阻尼器的阻尼力模型;最后,将该阻尼力模型及其参数与试验结果和双线性强化模型进行了比较,验证了R-O理论模型的有效性,并分析了误差存在的原因。
Based on Ramberg-Osgood constitutive model (R-O model) of mild steel, damping force hysteresis loop models of X type and triangle mild steel dampers are derived from classic mechanical principle directly. Firstly, the R-O stress-strain relationship of mild steel is given under cyclic loading. Secondly, damping force hysteresis loop models for mild steel plate damper are deduced under considering the R-O constitutive model. Finally, the comparison of R-O model and experiment and double linear model is carried out. And then the effectiveness of this model is verified. Moreover, the reason of errors is analyzed.
