Magnetic rheology elastic body active-passive integrated damper based on extrusion type applied force

The invention relates to a magnetorheological elastomer active and passive integrated damper based on an extrusion type stress, which belongs to the structure vibration isolation and control field, wherein a magnetorheological elastomer is arranged in a magnetic conductive sleeve; the upside of the magnetorheological elastomer is connected with a joint lever; the lower part of the magnetorheological elastomer is fixedly connected with a lower positioning plate; a groove is arranged on an outer circumferential surface of the magnetic conductive sleeve positioned in a permanent magnet, embedded with a coil winding and positioned and fixed by an upper positioning plate and the lower positioning plate; the permanent magnet, the upper positioning plate, the lower positioning plate and the lower part of the joint lever are arranged in an outer magnet isolating cylinder; the upside of the outer magnet isolating cylinder is provided with an upper end closure; the upper part of the joint lever extends out from a pylome of the upper end closure and is connected with a controlled object; a pretightening spring is sleeved on the joint lever; the bottom of the outer magnet isolating cylinder is provided with a lower end closure; a sensor is fixed on the joint lever and connected with a power amplifier through a control unit module; the power amplifier is connected with the coil winding through cables. The magnetorheological elastomer active and passive integrated damper has large bearing capacity, a simple structure and can be automatically suitable for active and passive vibration control and has wide application range.
