The invention discloses a high-speed rotation testing
machine and a method for testing the high-speed rotation strength performance of a rotor. The high-speed rotation testing
machine comprises a test cavity, a rotor
system which is accommodated in the test cavity and used for testing the test rotor, a driving
system that drives the rotor
system and a rotating
speed control system that controls the rotating speed of the rotor system, wherein the driving system includes a driving motor and a speeder which is connected with the driving motor and drives the rotor system to rotate at a high speed, the rotor system includes a test rotor fixed part, a main shaft connected with the test rotor fixed part and driven to rotate by the speeder, and a
damper which is sleeved outside the main shaft and supports the main shaft, the test cavity is equipped with a vacuumizing opening, a plurality of
layers of containing rings is arranged in the test cavity and surround the rotor system, and the containing rings are connected through spacing blocks arranged at
tail ends of the containing rings. The high-speed rotation testing
machine uses a high-speed rotating rotor as a
test object, the rotor is speeded up through the speeder system, the working condition of the rotor in high-speed rotation is simulated, and the
performance requirement of high speed centrifugal load effect resistance of the rotor is tested.
