Abstract

The invention discloses a high-power magnetorheological constant acceleration soft start device and a control system thereof, and belongs to the field of magnetorheological fluid transmission. The high-power magnetorheological constant acceleration soft start device and the control system thereof comprise a device part and a control part. The device part is in a double-disc magnetorheological fluid transmission mode, the working faces of two transmission discs are provided with radial strip grooves, the space between the two discs is filled with magnetorheological fluid, and a magnet exciting coil is wound around the two discs. The control part is composed of a data processor, a master controller, a sensor, a current controller and a hydraulic cylinder control valve. The largest torsional moment of the magnetorheological soft start device is improved by pressurizing the magnetorheological fluid and changing the surface structures of the inner wall faces of the two discs, and a constant acceleration soft start system is controlled in the starting process.

Description

technical field [0001] The invention relates to a magneto-rheological soft-starter, in particular to a high-power magnetorheological constant-acceleration soft-starter and a control system thereof. Background technique [0002] Magnetorheological fluid is a new type of intelligent material, which exhibits low-viscosity Newtonian-like fluid properties when there is no external magnetic field. In the case of an external magnetic field, the liquid form with good rheological properties can be turned into a solid-like material within milliseconds, and once the magnetic field loses its effect, it will return to the liquid state. Under the action of a magnetic field, the magnetic particles in the magnetorheological fluid can form microstructures such as through chains, branched chains, isolated chains, and columnar chains, and the ends of various microscopic chain structures are easy to break. Therefore, simply relying on shearing Mode is difficult to increase the yield strength o...
