The invention discloses a multi-loop asymmetric magnetorheological damper. The multi-loop asymmetric magnetorheological damper comprises a barrel, a left end cover, a right end cover, a piston mechanism and a piston rod, wherein the left end cover and the right end cover are arranged at the two ends of the barrel, the piston mechanism is arranged inside the barrel, the piston rod is connected with the piston mechanism, and can drive the piston mechanism to reciprocate, the piston mechanism comprises a piston assembly, a valve plate assembly and a valve body assembly which are sequentially arranged from left to right in the axis direction of the barrel, the valve body assembly is connected with the piston rod, and the piston rod drives the piston mechanism to reciprocate so as to form different magnetorheological fluid circulation loops. The magnetorheological damper of the technical scheme meets the requirements that the required damping force range is large and the required force values are different under t
