Effects of Pre-strain, Strain Amplitude and Frequency on Dynamic Compressive Properties of Magnetorheological Elastomeric Composite
Original language description
Dynamic compressive properties of isotropic magnetorheological elastomeric composite (MEC) under cyclic compression loading have been studied in this paper. Effects of pre-strains from 5 to 20%, strain amplitudes from 0.01 to 0.04, and excitation frequencies from 10 to 50 Hz on the dynamic properties of isotropic MEC under harmonic cyclic compression loading were examined. Results showed that the storage and loss moduli of the isotropic MEC decreased with increasing the strain amplitude, but they enhanced with the rise of the pre-strain and frequency. Although the storage modulus of the MEC changed slightly over time, the loss modulus reduced somewhat with increasing time. The reduction in the loss modulus of the MEC under cyclic compression loading is attributed to increasing material temperature during the testing. Besides, despite the loss angle tended to reduce over time, it changed irregularly with raising the pre-strain, strain amplitude, and frequency as well. In general, the dynamic compressive properties of the MEC strongly depended on the pre-strain, strain amplitude, and frequency of cyclic loading.
