| 摘 要： | 基于链化模型的磁流变弹性体,在受到压缩形变时,基体中的颗粒链会弯曲变形,变形后相邻颗粒间的相互作用力沿压缩方向和垂直于压缩方向的分量均不同。分析了压缩模式下链弯曲对磁流变弹性体磁致压缩模量的影响。随着磁场强度和压缩应变的增大,磁流变弹性体的磁致压缩模量在压缩方向的磁致力分量和垂直于压缩方向的磁致回复力的共同作用下逐渐变大。

| Abstract: | The particle chains of magnetorheological elastomer based on the chain-like model will bend under the effect of compression.The component of the interaction force between the compressive direction and perpendicular to the direction of compression is different after deformation.In this study,influence of chain bending on the magneto-induced compressive modulus was analyzed under compressive mode.The result indicated that the magneto-induced compressive modulus of magnetorheological elastomer gradually increases with the increasing of magnetic field strength and compressive strain,which is due to the effect of the component of magneto-induced force along the compressive direction and magneto-induced restoring force along perpendicular to the direction of compression. |
