The application discloses a fan shaft simulation device and a measuring method of a two-stage fan impeller, and belongs to the fan impeller measuring field. The application provides a fan shaft simulation device and a measuring method of a two-stage fan impeller, adopts an asymmetric supporting structure to realize the centering of a two-stage fan wheel disc, completes the positioning of an integral ring structure casing on the same side, and simultaneously satisfies the requirements of fan unit body measurement in a horizontal state and bearing clearance elimination. The simulation device with the fan shaft can be connected to a turnover frame to realize the overall turnover function, satisfies the process of vertical assembly-horizontal measurement, and is safer and more reasonable for the assembly of the rotor and the casing; the assembly can eliminate the bearing axial clearance on the simulation device, and the top tool does not need to be newly manufactured and arranged; the simulation device with the fan shaft becomes an integrated device after the first assembly and detection, is easy to maintain, can be repeatedly used for component assembly, and indirectly saves the assembly period.
