Electromagnetic damper

Abstract

The invention relates to an electromagnetic damper. The electromagnetic damper is used for an airplane telex accelerator platform and has reliable and stable system damping force under a telex manipulative mode. When the telex manipulative mode is adopted by the airplane accelerator platform, the load of a steel rope, an engine main pump and other links is eliminated, therefore, a damping system must be added to the telex accelerator platform and is connected to a revolving point of a transmission periodic line in parallel for replacing the load, it is ensured that a pilot can still normally push and pull a handle of the accelerator platform according to the original manipulative force, and the size of an engine throttle is controlled. The electromagnetic damper is characterized by being small in size, convenient to install and stable in damping force, moreover, the damping force can be adjusted externally, and the requirement for using of the accelerator platform is met.

Description

technical field [0001] The invention relates to an electromagnetic damper, which is used for an aircraft fly-by-wire accelerator console and has reliable and stable system damping force in the fly-by-wire control mode. Background technique [0002] With the continuous development of aircraft fly-by-wire engines and fly-by-wire control systems, the aircraft throttle console is gradually upgraded from a complex mechanical control mode to a fly-by-wire control mode, thereby effectively reducing the transmission link of the aircraft throttle control system, reducing the weight of the aircraft, and redundant The degree of design improves the reliability of the system. [0003] When the fly-by-wire control mode is adopted for the throttle console of an aircraft, the loads of the steel cable and the main pump of the engine will be removed. Therefore, the damping system must be added to the throttle console of the fly-by-wire console, and it must be connected in parallel to the turn...

AI Technical Summary

Problems solved by technology

[0004] There are two types of dampers commonly used in throttle consoles. The friction plate damper uses the boundary friction between copper and steel to realize the damping force. It takes a long time for the process to run in, and the damping force cannot be adjusted externally, that is, the pilot can adjust the damping force of the throttle console in any state according to his own situation; the permanent magnet damper is composed of two sets of permanent magnet components, and the permanent magnet component One is the stator and the other is the rotor. The rotor rotates and cuts the magnetic field lines to generate a damping force. The disadvantage is that the volume is large and there is a strong sense of frustration when rotating.
