The existing commercial rheometer cannot satisfy the demand of the high shear rate and stress data of Magnetorheological glue. To solve this problem, a testing device with airtight cylinder shear mode is designed to measure the parameters of Magnetorheological Glues in this study. Based on the overall structural design, the relationship of the exciting current and the magnetic field is obtained by establishing the analytical model of magnetic circuit in shear channel. The relationship is verified by the finite element simulation. Considering the tilt between the rotor and outer cylinder, the torque transmission mechanical model is proposed to get the theoretical relationship between the incline angle and the error of torque transmission. The prototype of testing device is fabricated and the tests for Magnetorheological glue are executed. The experimental data by testing device agree with those by Anton Paar rheometer at the low shear rates. It shows that the test device can reach the measurement with high shear rate of 25 000 s-1 and high shear stress of 200 kPa.
