Abstract: A new MR material, named as o-rheological viscoelastic fluid (MRVF), is put
forward. The carrier of MRVF is based on the chemical products of hexamethyldisiloxane and
polyborodiphenylsiloxane. By means of ball milling method and special additives, four samples
are developed. The rotary rheometer, Austrian Anton Par MCR-301, is used to test the mechanical
properties of the samples. The experimental results show that the shear stress varies from 5kPa to
120kPa with the shear rate of 200s-1 and ic induction intensity of 0~. According to the
curves of shear stress versus shear rate ,the shear thining and yi
