Device for detecting frictional wear characteristics of magnetorheological fluid under magnetic field

The invention relates to a device for detecting frictional wear characteristics of magnetorheological fluid under a magnetic field. In a magnetic induction coil of a magnetic generating module of the device, a copper enamelled wire is used as a lead, magnetic conduction low-carbon steel is used as a winding shaft, and an aluminum product is used as a baffle plate, so magnetic loss is reduced effectively, the stability of the operation of the magnetic field is improved, and a detection platform is provided for the evaluation of the frictional wear characteristics of the magnetorheological fluid under the magnetic field. In the device for the frictional wear characteristics of the magnetorheological fluid under the magnetic field, an induction magnetic field which is perpendicular to the motion direction of a friction pair can be formed at a contact point of the friction pair according to test requirements, the variable regulation of the magnetic field can also be realized by changing a value of current inputte
