Abstract
Abstract-Magneto-rheological elastomer (MRE) mechanism model based on chain structure has been widely concerned. However, the experimental results indicate that the internal chain of MRE, under the external magnetic field is not straight or oblique. Therefore, a novel 'S' chain structure mechanism model is proposed, which is more practical by studying the microscopic effects of internal magnetic particles due to adsorption and chain formation and extrusion repulsion. The model combines the fully coupled magnetic field, particle distribution characteristics correction and lateral shrinkage of the material, thus can reveal the influence of magnetized particles on the total magnetic field strength, the uneven distribution of particles in the initial chain formation and the effect between adjacent chain particles. The proposed ’S’ chain model is verified with the test results. This work provides an important theoretical basis for MRE configuration and application.
