Description
Technical Field
The utility model relates to the field of mechanical technology, especially, relate to a shimmy damper test equipment.
Background
The shimmy damper is used for preventing the shimmy phenomenon of the front wheel when the airplane moves on the ground. Because the front wheel of the airplane can deflect left and right, and the undercarriage of the metal structure is an elastic body, the airplane wheel receives the action of ground friction force, if the airplane encounters interference in straight-line running, the front wheel deviates from the original motion direction, and the front undercarriage is likely to generate a left and right deflection oscillation phenomenon by taking the original motion direction as an axis under the alternating action of the ground friction force and the self elastic force. If the aircraft is rolling at a low speed, the oscillations can converge on their own without serious consequences. However, if the speed of the airplane is increased to a certain value, the oscillation tends to diverge, the amplitude is increased, the abrasion of the airplane wheel is increased, the sliding direction is difficult to control, the reading of a cockpit instrument is not clear, and the landing gear structure can be damaged in serious conditions, so that the flight safety is endangered. To prevent shimmy, almost all aircraft have shimmy dampers mounted on the nose landing gear as part of the nose wheel steering system.
However, there is currently no tool for shimmy damper performance testing.
