Viscous damping is damping that is proportional to the velocity of the system. That is, the faster the mass is moving, the more damping force is resisting that motion. Fluids like air or water generate viscous drag forces. Figure \(\PageIndex{1}\): A diagram showing the basic mechanism in a viscous damper.
Damped Free Vibration refers to the oscillation of an object where the amplitude decreases over time. There are three states of damped vibration: underdamped, critically damped and overdamped. Applications of Damped Free Vibration can be seen in diverse fields, such as automotive engineering, civil engineering and electronics.

27 Μαΐ 2024 · If \(\Delta=0\) we are dealing with critically damped free vibration with \(y_{e}=A_{0} e^{-\frac{c_{e}}{2 m_{e}} t}+A_{t} t e^{-\frac{c_{e}}{2 m_{e}} t}\). Two initial conditions of the form \(y_{e}\left(t_{1}\right)=y_{1}\) or \(\dot{y}_{e}\left(t_{2}\right)=v_{2}\) need to be solved to determine the two unknown constants in the solution ...
Viscous damping is the most used damping mechanism in vibration analysis. When mechanical systems vibrate in a fluid medium such as air, gas, water, or oil, the resistance offered by the fluid to the moving body causes energy to be dissipated.
Free Vibrations. We begin by examining the response of the single-degree-of-freedom (SDOF) system with no external forces. The mass is set into motion by an initial displacement from its at rest position and/or an initial velocity.
In this section, we explore the influence of energy dissipation on free vibration of a spring-mass system. As before, although we model a very simple system, the behavior we predict turns out to be representative of a wide range of real engineering systems.
