The invention relates to a centrifugal deformation compensation method of complex-shaped rotors on the basis of reversed-field force loading, which comprises the following steps: (1) establishing an ideal geometric model to the rotor in Ansys simulation software under a high-rotation-speed work situation; (2) applying a high-gradient force field to the rotor, wherein the direction of the force field towards the rotation axis of the rotor, namely, a reversed-field force is applied to the rotor; (3) performing simulation calculation; (4) obtaining geometric parameters of the rotor after deformation under the reversed-field force loading conditions; (5) designing the geometric structure of the rotor according to the deformation parameters to enable the geometric shape of the rotor having the new structure to be an ideal shape under the work conditions, namely, centrifugal deformation compensation to the rotor is achieved. The invention belongs to the field of computer aided design and manufacturing. The method can be used for the centrifugal deformation compensation to high-precision gyrorotors and can increase the measurement precision of the gyrorotors.
