Abstract

The invention discloses an environment-friendly aviation skin damper, and relates to the technical field of aviation. The environment-friendly aviation skin damper comprises a steel plate, and the upper side surface of the steel plate is fixedly connected with a damping reinforcing patch. According to the environment-friendly aviation skin damper, the bending vibration strength of a metal component is weakened through the damping reinforcing patches, and when the metal component is bent and vibrates, vibration energy is rapidly transmitted to the damping reinforcing patches coated on the metal component, so that internal friction and mutual dislocation of the damping reinforcing patches are caused, then most of the vibration energy is changed into heat energy to be consumed, the noise energy radiated by bent vibration is reduced, meanwhile, the damping reinforcing patches can further shorten the excited vibration time of the metal component, equivalently, the total energy of noise radiated by the metal component is reduced, and therefore the problems of fatigue damage of aircraft structures and failure of electronic equipment due to the fact that multi-peak resonance of naval vessels, aircraft structures and electronic equipment thereof is frequently excited due to the fact that broadband vibration sources generated in the using process of existing aircrafts are too large are solved.
