Dynamic Compressive Behavior of an Anisotropic Magnetorheological Elastomeric Composite

Popis výsledku v původním jazyce

The dynamic mechanical behavior of an anisotropic magnetorheological elastomeric composite (aMEC) made of silicone rubber and micro-sized carbonyl iron particles (CIPs) was investigated via cyclic compression tests. The dependence of aMEC dynamic moduli on frequencies (1–50 Hz) at various pre-strains (5–20%), strain amplitudes (0.1–3%), magnetic field intensities (0–0.296 T), and temperatures (RT-60 ℃) were studied experimentally. Experimental results showed that the storage modulus of aMEC was increased with increasing frequency to 50 Hz. The loss modulus was enhanced with rising frequency to about 20 Hz, then changed irregularly. Besides, the storage and loss moduli rose with increasing pre-strain and magnetic field intensity but reduced with rising strain amplitude and temperature. Moreover, the change of aMEC dynamic moduli with frequency at various pre-strains, strain amplitudes, magnetic field intensities, and temperatures was numerically examined using a fractional derivative hybrid Maxwell and Kelvin-Voigt viscoelastic model. The investigated model was fitted very well to the storage modulus of aMEC. The present model parameters were identified by fitting simultaneously the storage and loss moduli to measured data of aMEC. In general, the fractional hybrid Maxwell and Kelvin-Voigt model can be applied to simulate the dynamic compressive behavior of aMEC.
