摘要：

Electrorhelogical fluids(ERF) behave excellent anti-vibration performance based on the controllable damping characteristic. However, it is difficult to establish an accurate control strategy because of the complexities of the dynamics of ERF under different vibration amplitude, vibration frequency and different electric field strength. Through the testing experiment on the dynamic performance of anti-vibration structures containing electrorheological fluids(ERF), an analysis model is established for studying the dynamics of ERF based on the hysteresis curves. By observing the hysteresis curves acquired by excitation experiments, the dynamics of the ERF based anti-vibration device can be analyzed. According to the analysis results, the dynamics of ERF are classified into five categories: Newton viscous liquid, pre-yield elastic body, pre-yield viscoelastic body, nonlinear body and post-yield viscous body. At the same time, the occurrence conditions of ERF behaving the different dynamics and influence of ERF to the dynamics of the global structure are discussed.
