摘要
针对Kevlar绳索准静态加载下出现的非对称迟滞效应,建立能够灵活控制迟滞环形状的推广Bouc-Wen模型以描述高度非对称的迟滞现象.结合数学模型与试验结果特点提出适用于该模型的分步参数识别方法,通过提出的识别方法得到试样模型参数,采用数值计算方法求解模型得到在循环载荷作用下的理论迟滞曲线.结果表明,理论计算值与试验值较吻合,证明了模型的正确性与识别方法的有效性.
A generalized Bouc-Wen model with flexible shape control was proposed to describe the asymmetric hysteresis effect of Kevlar tether under quasi-static loading.An appropriate method to identify the model parameters step by step was developed by combining the mathematical model with the features of the experimental data.Theoretical curve under cyclic load was calculated using numerical method.Results showed that the experimental data fitted well with the theoretical curve,which verified the correctness of the model and the validity of the identification method.
