颗粒链取向对磁流变弹性体磁致剪切模量的影响

为分析内部颗粒链与外加磁场间取向夹角对磁流变弹性体(MRE)磁致剪切模量的影响，将磁化颗粒视为磁偶极子，仅考虑同一链内磁化颗粒间相互作用，推导了MRE磁致模量的微观模型，在微观层面研究了取向角度对磁致模量的影响。制备了具有不同颗粒链取向角度的MRE试样并进行测试，结果表明微观模型预测趋势与测试结果一致。对该模型进行简化并识别其参数，得到基于参数的磁致模量模型，可预测磁致模量的实际值。

Effect of particle chain orientation on MRE magneto-induced shear modulus

In order to analyze the effect of the orientation angle between the internal particle chain and the external magnetic field on the magnetorheological elastomer (MRE) magneto-indced shear modulus, the magnetized particles were described as magnetic dipoles,and only the interaction between the magnetized particles in the same chain was considered. The micro-model of magneto-induced modulus of MRE was deduced, and the trend of magneto-induced modulus changing with orientation angle was predicted at the micro-level. MRE samples with different orientation angles of particle chains were prepared and tested. The results show that the predicted trend of the microscopic model is consistent with the experimental results. The model was simplified and its parameters were identified to obtain a parameter-based model of magneto-induced modulus of MRE, which can predict the actual value of magneto-induced modulus.
