摘要
Bouc-Wen模型是较有代表性的微分型滞回模型,具有通用性强和参数易识别的优点,对各种光滑的滞回曲线都能较好地近似描述。利用非线性系统动力学、电路等理论,将Bouc-Wen数学模型转化成电路模型,通过仿真验证设计的Bouc-Wen电路模型的正确性,并制作实物电路板。针对Bouc-Wen滞回电路板设计实验数据采集系统,通过对电路的调试,使电路板的输出和之前的仿真结果相一致,验证电路板的可行性。
Bouc-Wen model is a kind of differential hySteretic model, which has the advantages of wide universality andeasily recognizable parameters for better approximate description of hysteretic curves. The validity of the designed Bouc-Wen circuit model is verified through simulation by using nonlinear system dynamics and circuit theory, transforming math-ematic model into circuit model, and a physical circuit board is made. An experiment based on data acquisition system bycircuit debugging shows that the output of the circuit board agrees with the simulation result, which can prove the feasibilityof the circuit board.
