Control on Dynamic Response of Fluid-driven Deployable Mechanism by Application of Magnetorheological Elastomeric Materials
A kind of intelligent materials named magnetorheological elastomers (MREs) is applied on the surface of a rotating plate to avoid resonance vibration and to attenuate the vibration amplitude. Under a variable magnetic field,the stiffness of structure with MREs can be changed in wide range. First,the field-induced shear modulus is numerically studied and compared with the experimental results. Then,other equivalent parameters in nonlinear material equation of MREs are determined. Finally,the vibration suppression effect is verified through numerical simulation of the dynamic impact response of rotating plate in a fluid-driven deployable mechanism subjected to impact loads. On the condition that the weight of the plate is fixed,its vibration response is suppressed in shorter time than original design.
