Reverse Design of a Novel Coupling Strut for Vibration Attenuation in the Helicopter Cabin

Reverse Design of a Novel Coupling Strut for Vibration Attenuation in the Helicopter Cabin

Helicopter gearbox support strut is one of the main research objects in the field of vibration and noise control in helicopter cabins. Aiming to further widen the vibration attenuation range of traditional Bragg periodic struts, a novel type of Local resonance (LR)/Bragg coupling periodic strut with...
