基于QSSE方法的橡胶隔震支座参数识别
Parameter Identification of Rubber-Bearings Based on QSSE Method
摘要
Abstract
Parameter identification of nonlinear rubber-bearing isolators is investigated using quadratic sum-squares error (QSSE) method. Classic Bouc-Wen models are established to describe the dynamic character of the rubber-bearings. Further, experimental tests using a particular type of rubber-bearing are conducted. Based on experimental data, QSSE method is used to identify model parameters. The results show that the estimated parameters obtained by QSSE method are identical in different scenarios (i. e. , different excitations and Bouc-Wen models with different amount of parameters). Besides, the i-dentified displacements match the experimental ones well. Research results demonstrate that QSSE method is effective and accurate for parameter identification of nonlinear hysteretic rubber-bearings. Bouc-Wen model has the ability to describe the nonlinear behavior of rubber-bearings, and the model simplifying is reasonable.关键词
