Environment-friendly aviation skin damper

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.

Description

technical field [0001] The invention relates to the field of aviation technology, in particular to green and environment-friendly aviation skin damping. Background technique [0002] Aviation is a complex and strategic human activity, which refers to the flight activities of aircraft in the earth's atmosphere (air space) and related scientific research and education, industrial manufacturing, public transportation, aviation sports, national defense military, government management Through the use of air space and aircraft (aircraft), aviation activities can be subdivided into many independent industries and fields, such as aviation manufacturing industry, civil aviation industry, etc. It is often seen that people from their respective The use of this word in the field, the connotation of this word is extremely rich and changeable, and with the rapid development of modern aviation and spaceflight, the power and acceleration of ships and aircraft systems have been greatly impro...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides green and environment-friendly aviation skin damping, which solves the problem that the broadband seismic source generated during the use of today's aviation aircraft is too large, which often stimulates the multi-peak resonance of ships, aircraft structures and their electronic equipment. Causes fatigue damage to aircraft structures and failure of electronic equipment
