The invention provides a dynamic torque calibration device driven by a torsion bar, and belongs to the field of metering and testing. The problem that existing dynamic torque calibration cannot meet the torque metering requirements of various industrial fields is solved. The dynamic torque calibration device adopts a horizontal arrangement structure and comprises a torsion bar, a to-be-measured torque sensor, a grating encoder, a mechanical bearing support load shaft and a standard quality module, the to-be-measured torque sensor comprises a rotor part and a stator part, and the rotor part and the stator part are connected through wireless communication. One end of the torsion bar is mounted on the side wall of the base, the other end of the torsion bar is connected with one end of a rotor part of the torque sensor to be tested, and the other end of the rotor part of the torque sensor to be tested is sequentially connected with the grating encoder, the mechanical bearing support load shaft and the standard qu
