Abstract: Short-fiber reinforced Magneto-rheological rubber is a kind of multi-coupled composite magnetic bombs,it is by the magnetic particles,short fibers,rubber elastic material,has a magnetic field controllable shear modulus changes in an external magnetic field real-time control.It can be widely used in active vibration control.In this paper,from a practical point of view through the Experimental study of Magneto-rheological rubber materials under different parameters of the mechanical properties,Including the magnetic field strength,iron particle volume fraction,short fiber components and the application environment on the Magneto-rheological rubber modulus and loss Factor,for the design and application of natural rubber short fiber-enhanced Magneto-rheological rubber to provide the necessary reference.
