Web15.2: Viscous Damped Free Vibrations. 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 : A diagram showing the basic mechanism in a viscous damper. WebFeb 3, 2024 · Forced vibrations are the vibrations produced in a body by applying an external periodic force having a frequency, normally different from the natural frequency of the body. A body or a system, capable of vibrating can also be made to vibrate at any desired frequency.
