Modelling and experimental characterisation of a compressional adaptive magnetorheological elastomer isolator

This article proposes a simple physical-based model to describe and predict the performance of axially compressed magnetorheological elastomer cylinders used as vibration shock absorbers. The describes macroscopic stiffness changes because an externally applied magnetic field from microscopic composite cell silicone rubber carbonyl iron particle. Despite neglecting material hyperelasticity, anisotropy adjacent interaction, effectively effect on modulus elasticity. in mechanical properties with induced are measured samples different particle concentration based volume percentage, that is, 10 30 percent particles matrix. manufacturing process is detailed, well experimental validation effective change under terms transmissibility mobility testing. However, prediction seems be limited by linear elastic model. Predictions measurements compared, showing capable predicting tunability dynamic/shock absorber proposed devices have possible application reduction vibrations.
