Vibration Suppression of a Helicopter Using Pendulum Absorbers : First Elastic Mode of a Blade

Autor: Naoki Fujimatsu, Yukio Ishida, Imao Nagasaka, Takayuki Koyama

Publikováno v: Journal of System Design and Dynamics. 4:837-847

Centrifugal pendulum vibration absorbers are widely used as a vibration suppression device for helicopters. The vibration characteristics of this absorber have been investigated by utilizing linear anti-resonance theory. However, it has been noted th
