| Abstract: | Magnetorheological elastomer(MR elastomer,MRE) based on polyurethanes was prepared and a dynamic experimental device was fabricated to study the compression properties of MR elastomer.Using vibration theoretical,a model for the dynamical characteristics of MRE was established.Based on the model,a method used to compute the MR effect was put forward to investigate the squeeze characteristics of MRE under different pre-compressed load,different amplitude and frequency,different magnetic field.The results show the MR effect increases with the magnetic field and the amplitude.But the frequency has no obviously effect on the MR effect.With the increase of precompressed load,the MR effect decreases sharply. |
