【摘要】 在实验数据的基础上建立了磁流变阻尼器输出力与不同定常电流控制量的关系,讨论了提高预测精度的方法,对修正Bouc-W en模型进行了进一步的简化修正。新的模型继承了Bouc-W en模型对激励的适应能力,没有使用修正Bouc-W en模型中参数随控制电压线性变化的函数,将控制量从Bouc-W en方程中分离了出来。本文模型的预测结果与实验数据相一致,表明本文提出的模型能准确地预测不同谐波激励和不同定常电流控制下的磁流变阻尼器输出力。更多还原

【Abstract】 A relationship between the damping force and control variable of Magnetorheological(MR) damper based on experiment data has been built.Based on the relationship and the Bouc-Wen model,a new model of MR damper has been presented in this paper.The new MR damper model keeps the advantage of Bouc-Wen model and avoids the linear function between control variable and model parameters used in the Bouc-Wen model.The predicting results of the new model agree well with the experimental results,indicating that the new model presented in the paper can accurately predict the damping force of MR damper under different excitation and different constant current.更多还原
