The invention discloses an air floating type dynamic torque calibration device and calibration method, and belongs to the technical field of metering. An excitation motor, a torque sensor to be measured, a third laser range finder, a fourth laser range finder, an air bearing and an auto-collimation light pipe are all installed on a base, a first laser range finder and a second laser range finder are installed at the left end and the right end of the top of the air bearing respectively, and the air bearing supports a load shaft and is supported by an inner ring of the air bearing. The rotor part of the excitation motor, the rotor part of the torque sensor to be measured, a first standard mass module, a first grating encoder, an air bearing supporting load shaft, a second grating encoder, a second standard mass module and a plane mirror are sequentially fixed and locked through high-strength screws from left to right to form a rotating shaft system. The auto-collimation light pipe is installed on the right side
