A sucker type magnetorheological damping system and method

Abstract

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 uncontrollable friction force always existing in the magnetorheological damper is reduced, the lower limit of controllable damping force of the magnetorheological damper is reduced, and the controllable range of the magnetorheological damper is widened.

Description

technical field [0001] The invention belongs to the field of dampers, and in particular relates to a sucker-type magneto-rheological damping system and method, which are suitable for vibration-reduction scenarios that do not destroy the integrity of the surface of a vibration-damped target. Background technique [0002] Magnetorheological dampers have been widely used in shock absorption and vibration isolation scenarios in various industries. In these scenarios, bolts, welding, etc. are used to connect the magnetorheological damper to the damped part. However, in some special occasions, such as: large skins, blades with complex curved surface features, casings and other parts need to use dampers to suppress their vibration in the processing engineering, but such parts cannot use the above-mentioned method to achieve magnetic Stable connection between the rheological damper and the damped part. In addition, since the design of the seal of the magnetorheological damper resul...
