Abstract

See full text

A magnetorheological fluid brake and a control method therefor. When braking is not required, the brake does not work, and no field coils are energized. When braking is required and the brake receives a retarding braking signal, a field coil module is energized, the current is gradually increased, an oil port is gradually closed, and a back pressure inside the brake is also gradually increased, thereby gradually increasing a braking force so as to achieve a braking effect. By using the characteristics of a pump and the characteristics of a valve for the magnetorheological fluid, the viscosity of the magnetorheological fluid is adjusted, such that a back pressure is generated in a pump body, which in turn imposes a braking torque on a shaft, thereby performing braking.
