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.
20 Φεβ 2013 · Damping removes energy from the system and so the amplitude of the oscillations goes to zero over time, regardless of the amount of damping. However, the system can have three qualitatively different behaviors: under-damping, critical damping, and over-damping.
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.
Studies of damping have a major role in vibration isolation in automobiles under random loading due to surface irregularities and buildings subjected to earthquake loadings. The recent developments in the flelds of robotics and active structures have provided impe-
7 Ιουν 2024 · Examples of damping include: Shock absorbers in vehicles. Seismic dampers in buildings. Vibration dampers on bridges. Types of Damping. Depending on the system’s nature, damping can occur through various mechanisms, such as frictional forces, air resistance, or electrical resistance. 1. Viscous Damping.
Damping is a frictional force, so it generates heat and dissipates energy. When the damping constant b is small we would expect the system to still oscillate, but with decreasing amplitude as its energy is converted to heat.
