Parameter identification of Bouc-wen model for MR damper based on genetic algorithm

LIU Yong-qiang,YANG Shao-pu,LIAO Ying-ying,ZHANG Geng-ning(Shijiazhuang Tiedao University,Shijiazhuang 050043,China)  
A Bouc-Wen dynamic model of magnetorheological(MR) dampers was considered and its parameters were obtained by using genetic algorithm(GA) based on mechanical characteristic experiments of a MR damper.Identification precision of GA was improved by gradually shrinking linear ranges of these parameters.Functional relationships between some parameters and applied current were determined by using curve fitting through analyzing their characteristic curves.The specific function expressions were derived by using GA.The identification results and curve fitting results were verified with experiment data in different amplitudes and frequencies.It is shown that the identification results by the method proposed are close to global optimum values,and the model identified can meet the need of engineering applications.
