Turbine blade tip clearance sensor calibration device and simulated impeller manufacturing method thereof

The invention discloses a turbine blade tip clearance sensor calibration device and a simulated impeller manufacturing method thereof. The sensor calibration device comprises a base frame (2), a displacement mechanism component (5), a motor (7), a simulation impeller (1) and a suction cup assembly. The displacement mechanism component is installed on the base frame, the motor is installed on the displacement mechanism component, the simulation impeller is installed on the motor, and the rotation axis of the simulation impeller is perpendicular to the displacement direction of the displacement mechanism component; the suction cup assembly is installed on the base frame. The manufacturing method of the simulation impeller comprises the following steps: manufacturing the simulation impeller with a reduced scale; a blade tip clearance signal time sequence curve of the simulated impeller is obtained through a blade tip clearance sensor; grinding the blades of the simulated impeller; and the time sequence curve of
