Aircraft pipeline vibration is an important fault that seriously threatens flight safety.It is of great significance to reduce the vibration level of aircraft pipeline and improve the reliability and safety of aircraft.Aiming at the vibration reduction of aircraft pipeline structure which is difficult to be constrained by pipe clamps,apipeline vibration absorber based on particle impact damping technique is designed.Through ingenious structural deign,the vibration absorber is conveniently clamped to the exi...
