磁流变弹性体在磁场作用下的时效性能对基于磁流变弹性体的智能设备的精确控制具有重要意义。本文研究了各向异性磁流变弹性体在不同阶跃磁场下的瞬态响应，包括磁场诱导存储模量（Δ G’）和损耗模量（Δ G″）。结果表明：在阶跃场加载阶段，随着时间的推移，Δ G′增大，而Δ G″减小。Δ G′迅速降至0，而在阶跃场去除阶段，Δ G″继续逐渐减小。提出了一种基于磁偶极子和粘弹性参数模型的综合模型来解释瞬态响应。磁流变弹性体在磁场作用下的时效性能对基于磁流变弹性体的智能设备的精确控制具有重要意义。本文研究了各向异性磁流变弹性体在不同阶跃磁场下的瞬态响应，包括磁场诱导存储模量（Δ G’）和损耗模量（Δ G″）。结果表明：在阶跃场加载阶段，随着时间的推移，Δ G′增大，而Δ G″减小。Δ G′迅速降至0，而在阶跃场去除阶段，Δ G″继续逐渐减小。提出了一种基于磁偶极子和粘弹性参数模型的综合模型来解释瞬态响应。
The time-dependent performance of magnetorheological elastomers (MREs) under a magnetic field is important for the precise control of smart devices based on MREs. Here, the transient responses of anisotropic magnetorheological elastomers, including magnetic field-induced storage modulus ( Δ G ′) and loss modulus ( Δ G ″), were investigated under different step magnetic fields. The results indicated that Δ G ′ increased over time while Δ G ″ decreased after the initial jump in the loading stage of the step field. Δ G ′ quickly dropped to 0, while Δ G ″ continued to decrease gradually in the removal stage of the step field. A comprehensive model based on magnetic dipolar and viscoelastic parameter models was proposed to explain the transient responses.The time-dependent performance of magnetorheological elastomers (MREs) under a magnetic field is important for the precise control of smart devices based on MREs.
