摘要：
In order to study the vibration isolation performance and control strategy of a magnetorheological elastomer isolator. The frequency shift characteristic of a magnetorheological elastomer isolator was tested by experiments based on sweep excitation. It is proved that the magnetorheological elastomer isolator possesses a wide frequency shift range. Based on the frequency shift characteristic curve of the magnetorheological elastomer isolator, an on-off control strategy for sweeping excitation was proposed. The on-off control strategy based on variable damping and stiffness was applied to harmonic and random excitation. The experimental results prove that the magnetorheological elastomer isolator has great vibration isolation effect for different forms of excitation under control strategy. The above works lay a foundation for the engineering application of magnetorheological elastomer isolators. © 2020, Editorial Office of Journal of Vibration and Shock. All right reserved.
