High-temperature dynamic calibration device and method for gap measurement system

The invention discloses a high-temperature dynamic calibration device and method for a gap measurement system, and belongs to the technical field of engine measurement. The invention discloses a high-temperature dynamic calibration device for a gap measurement system. The high-temperature dynamic calibration device comprises a high-speed rotor system, a static displacement measurement system, a dynamic displacement measurement system and a heating system, the high-speed rotor system realizes dynamic simulation of an engine rotation environment. The static displacement measurement system provides a static standard clearance between the tip end face of the calibration disc blade and the end face of the calibrated tip clearance measurement sensor probe before the calibration disc rotates. The dynamic displacement measuring system is used for measuring and calculating dynamic lower gap variation and high-temperature elongation caused by factors such as vibration and shaft deviation before and after rotation of th
