Abstract：The blade mounted magnetorheological fluid retarder has not been used in the vehicle. This study carries out research work from the aspects of theoretical analysis，structural design and experimental test. The SC-810 motor test and analysis system is used to solve the problem of rapid demagnetization of the magnetic field of the blade mounted magnetorheological fluid retarder. The research results show that the magnetic field intensity and current show a linear relationship，which can accurately control the deceleration effect. It is proved that the retarder is feasible in vehicle application.
