However, due to the inductance of the coil, there will always be a lag time when the valve port is opened and closed, and this time is related to the structure of the valve. To change the lag time, the structure of the valve needs to be changed.

The invention discloses a novel magneto-rheological digital valve and a control method thereof. From another aspect, a novel magneto-rheological valve structure is provided, enabling the magneto-rheological valve to have a very large control range. Not only large-flow control can be realized, small pressure-difference flow control can also be carried out. Meanwhile, for the opening and closing of a valve opening, due to the limitation of the self structure of the valve, the cooperative work of three power supplies is adopted, and delay time can be reduced on the original basis. Through adopting the magneto-rheological valve structure different from the original structure, the control range of the magneto-rheological valve is greatly increased. Meanwhile, the novel magneto-rheological digital valve has excellent air tightness, can apply various control modes and is suitable for various occasions. When magneto-rheological fluid is not used, the novel magneto-rheological digital valve can become a high-speed digital switching valve and has rapid response time.
Description
technical field [0001] The invention belongs to the technical field of hydraulic control valves and control methods thereof, and in particular relates to a magnetorheological hydraulic control valve, a magnetorheological digital valve designed to improve the structure of the magnetorheological valve, and achieve better control by improving its control. performance. Background technique [0002] The magneto-rheological valve controls the flow rate of the valve by controlling the current of the excitation coil. However, since the magneto-rheological valve has no moving mechanical parts, the control range is small and the applicability is also limited. [0003] Since the hydraulic control range of the magnetorheological valve is mainly affected by two aspects: [0004] (1) The angle between the flow direction of magnetorheological fluid and the direction of magnetic field [0005] (2) The liquid flow channel of the magnetorheological fluid in the magnetic gap space. For (1),...
