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.

    本发明公开了绿色环保航空蒙皮阻尼,涉及航空技术领域,其包括钢板,所述钢板上侧面固定连接有阻尼补强贴片。该绿色环保航空蒙皮阻尼,通过阻尼补强贴片减弱金属构件弯曲振动强度,当金属构件弯曲振动时,振动能量迅速传给涂贴在其上的阻尼补强贴片,进而引起阻尼补强贴内部摩擦和相互错动,进而使振动能量大部分变成热能而损耗掉,进而降低弯曲振动所辐射的噪声能量,同时阻尼补强贴也可缩短金属构件被激励的振动时间,相当于减少了金属构件辐射噪声的总能量,从而解决了现今航空飞行器在使用过程中产生的宽带震源过大进而常常激发起舰艇、飞行器结构及其电子设备的多峰谐振引起航空器结构疲劳破坏以及电子设备失效的问题。
