摘　　要：为了更好研究磁流变阻尼器在隔振系统中的隔振性能与控制策略,以八极轴向绕组式磁流变阻尼器为控制对象,搭建磁流变阻尼器与压缩弹簧并联的隔振平台,利用电动振动台施加正弦位移激励,测试隔振平台在不同励磁电流、激振频率下的加速度传递率。根据测试结果设计模糊控制器,控制系统的输入为加速度传递率与激振频率,输出为磁流变阻尼器的阻尼力,最后对隔振平台进行正弦位移扫频的隔振实验。实验结果表明,在隔振平台发生共振的区间频率9.4~11.4Hz内,所设计的控制算法能减小加速度传递率14.3%以上。该研究可为磁流变阻尼器在隔振领域中的工程应用奠定基础。In order to study the vibration isolation performance and control strategy of the Magnetorheological(MR)damper in the vibration isolation system,a vibration isolation platform of the MR damper connected in parallel with the com-pression spring was constructed with the eight-pole axial winding MR damper as the control object.The platform used an electric vibration bench with a sinusoidal displacement excitation to test the acceleration transmissibility of the vibration iso-lation platform under different excitation currents and excitation frequencies.According to the test results,a fuzzy control al-gorithm was designed,the input of the control system was set as the acceleration transmissibility and the excitation frequen-cy,while the output was set as the excitation current of the MR damper.Finally,the displacement sweep frequency excitation experiment was done on the vibration isolation platform.The experimental results show that the designed control algorithm can effectively reduce the acceleration transmissibility by more than 14.3%in the resonant frequency range of 9.4-11.4 Hz.This research can provide a foundation for the engineering application of MR dampers in the field of vibration isolation.
