This review summarizes the basic principles of vibration control and analyses the vibration control strategies for different damping materials and damping structures. Meanwhile, various models of bio-damped structures are outlined.
Vibration isolation, damping, cushioning and dynamic vibration absorption are common passive vibration control methods, which efectively control the amplitude of vibra-tion and reduce impact energy, playing a positive role in limiting the hazards caused by vibration.
Critical damping viewed as the minimum value of damping that prevents oscillation is a desirable solution to many vibration problems. Increased damping implies more energy dissipation, and more phase lag in the response of a system. Reduced damping means more oscillation, which is often undesirable.
Damped vibration: The system is considered damped if energy dissipation occurs in the presence of damping components during vibration. From: Vibration of Functionally Graded Beams and Plates, 2016
28 Νοε 2019 · With damping, sufficient vibration strength of each oscillator has already been consumed and the resurgence is negligible. We now show an approach to determine the parameters that can realize CSD.
7 Ιουν 2024 · Damping refers to reducing or dissipating the energy of oscillations or vibrations in a system. The energy is dissipated usually in the form of heat, which leads to a gradual reduction in the motion of the oscillating system. Examples of damping include: Shock absorbers in vehicles. Seismic dampers in buildings. Vibration dampers on bridges.
The vibrations of linear 1 DOF systems with ordinary damping can be classified as underdamped, critically damped, and overdamped according to the magnitude of the damping coefficient. Critical damping is defined as the threshold between overdamping and underdamping.
