The invention discloses a rotor multi-blade and cartridge receiver fixed-point rub-impact simulation method considering cartridge receiver deformation. The method comprises the steps: S1, establishing a rotor and cartridge receiver system dynamics finite element model; s2, under the condition of cartridge receiver deformation, obtaining a gap function between the blade and the cartridge receiver; s3, taking rotor rotation and displacement of the blade and the cartridge receiver after deformation of the cartridge receiver into consideration, and obtaining a correction clearance function of the blade and the cartridge receiver; and S4, based on the corrected gap function of the blades and the cartridge receiver, setting time propulsion logic and time step change of rub-impact between the multiple blades of the rotor and the cartridge receiver, and calculating rub-impact force and rub-impact friction force between the blades and the cartridge receiver at each moment and rotor cartridge receiver system response.
