The invention relates to a laminated intelligent shock-isolation bearing capable of self-adaptively regulating cutting performance, the bearing is mainly composed of a magnetic assembly, a sensor (8) and a controller (9), wherein, the magnetic assembly is composed of magnetorheological elastomers (2) which are alternatively overlapped together, have the same shape and are sulfurized as a whole, a magnetically-conducting steel plate (3) and a coil winding (5) which is separated from the magnetorheological elastomers and is wound on a magnetically-conducting iron core (6), all of them are mounted between an upper connecting plate and a lower connecting plate to thereby form a complete closed magnetic circuit; a large deformation soft magnetic material (7) is arranged in the middle of the magnetic circuit; the sensor is mounted on the top of the upper connecting plate (1) and the controller is connected with the sensor and the coil winding via data lines, respectively. The invention can self-adaptively regulates the cutting performance thereof in accordance with external response; compared with ordinary rubber shock-isolation bearing, the bearing has small displacement among shock-isolation layers and strong controllability; and compared with intelligent complex shock-isolation system, the bearing has simple structure and good stability.
