Problems solved by technology
The rotor of the general free rock system is supported by mechanical bearings. Due to the friction of the mechanical bearings, the rotor is not completely free to move during the rotation process, but is restricted by the mechanical bearings, which affects the accuracy and credibility of the test results.

The five-degree-of-freedom active control maglev free rocking system is mainly composed of a maglev stator system and a maglev rotor system. The magnetic levitation stator system is mainly composed of the front section of the strut, the rear section of the strut, the cover plate, the rotary encoder, the coupling, the electromagnetic clutch assembly, the tension bolt, the fixed thread ring, the small self-locking thread ring, the large self-locking thread ring, the shaft Magnetic bearing stator, radial magnetic bearing stator, axial displacement sensor, radial displacement sensor; magnetic levitation rotor system mainly consists of limit joint, main shaft, protective bearing, radial magnetic bearing rotor, axial magnetic bearing rotor, axial sensor Detection ring, radial sensor detection ring. The invention adopts the magnetic suspension support mode, which greatly reduces the mechanical friction, enables the aircraft model to better simulate the real air flight of the aircraft, and greatly improves the accuracy of the wind tunnel test of the aircraft.
Description
technical field [0001] The invention relates to a five-degree-of-freedom active control magnetic levitation free rock system, which can be used in aircraft wind tunnel tests, and can analyze a series of aircraft swing, vibration, whirl, rotation, subsonic flight, sonic flight, supersonic flight, far supersonic flight, etc. The test makes the aircraft model better simulate the real air flight of the aircraft. Background technique [0002] Today's research on aircraft flying in the air is mainly to analyze various flight conditions of the aircraft in the air, such as air body flipping, wing flutter, wing rocking, high angle of attack takeoff and landing of the aircraft, and subsonic speed of the aircraft. Fly, fly at the speed of sound, fly at the speed of sound, fly far beyond the speed of sound. These studies have brought great inconvenience to the experiments. The free rock system was born according to the principle of the relative air motion of the aircraft in the air. ...
