Low frequency damping of metal panels in ambient Air [PDF]
, 2008 Mathematical models of structural dynamics are widely used and applied in many branches of science and engineering and it has been argued that many of the shortfalls with these models are due to the fact that the physics of joint dynamics are not ...

Damping force of air acting on vibrating elevator rope
Mechanical Engineering Journal, 2021 This paper describes the vibration damping characteristics of elevator ropes acted on by air. High-rise buildings sometimes resonate during earthquakes, and the elevator ropes in the building may swing significantly as a result. The vibration analysis of
