Sucker type magnetorheological damping system and method

The invention provides a sucker type magnetorheological damping system and method, and belongs to the field of dampers. The damping system comprises a sucker module, a magnetorheological damping module, a support module, a controller and a connecting module; the sucker module, the magnetorheological damping module and the support module are coaxially mounted in sequence, and are connected with thecontroller through the connecting module; the controller is used for driving each part of the damping system and acquiring signals acquired by the sucker module; the connecting module comprises a motor driving wire, a coil driving wire, a negative-pressure pump driving wire, a sensor wire and a negative-pressure hose; and through design of a magnetorheological fluid bypass and combination with the atmospheric pressure and a force sensing function of a piezoelectric sensor, the relative movement between a sealing piece of a traditional magnetorheological damper and a shaft or a hole is prevented, so that uncontrollabl
