The invention discloses a large dynamic output magnetorheological damper based on a ball screw, which relates to the technical field of dampers, and comprises a cylinder body, a piston assembly, a rotor assembly and a stator assembly, the piston assembly comprises a lead screw and a lifting lug connected with the lead screw, and the lead screw penetrates through the cylinder body and is connected with an external power source through the lifting lug to drive the lead screw to do linear motion in the cylinder body. The rotor assembly comprises a nut pair and a rotor fixed on the nut pair; the stator assembly comprises a plurality of stators and winding frames which are arranged at intervals, and the stators and the winding frames are fixedly connected and fixed in the cylinder body; when the screw rod linearly moves in the cylinder body, the rotor and the stator relatively rotate to shear the magnetorheological fluid; a magnetic field is generated around the winding frame, so that the magnetorheological fluid in the gap between the stator and the rotor generates a magnetorheological effect, and when the lead screw does linear motion to drive the rotor to rotate and the rotor and the stator rotate relatively, the magnetorheological fluid in the gap works in a shear mode and outputs large shear damping force outwards, and the working efficiency of the shock absorber is improved.
