Damping

  • The energy dissipation mechanism that causes vibrations to diminish over time and eventually stop.

  • Amount of damping mainly depends on the material, velocity of motion, and frequency of vibration.

  • Can be classified as:

  • Viscous Damping

  • Coulomb (or Dry-friction) Damping

  • Hysteresis (or Solid) Damping
