| 中文摘要 | 利用磁流变阻尼器特性试验数据,通过曲线拟合等手段建立了双sigmoid力学模型。该模型的参数是控制电流和振动频率、振幅的函数,能准确描述不同激励条件下阻尼力-速度滞回特性。建立了双层隔振系统模型,分析了阻尼比对传递函数的影响。提出了一种模糊半主动振动控制算法。仿真结果表明,该控制算法在宽频范围上能取得很好的隔振效果。; Double sigmoid model for MRD(magneto-rheological fluid damper) was developed based on the experimental study on MRD.The coefficients of the model were fitted as the functions of excitation conditions such as driving current and vibration frequency.The tests illustrate that the model is accurate and reliable under different excitation conditions.A two-stage vibration isolation system was built to study the influence of damping ratio on the isolation effect.Then a fuzzy semi-active vibration control strategy was proposed.Simulation results show that it greatly improves the vibration isolation effect in the wide range of frequency. |
