Overdamped damping ratio occurs when a system’s decay ratio (ζ) exceeds 1. In this condition, the system’s response to an external force is significantly slower and less oscillatory compared to underdamped or critically damped systems. The overdamped system gradually returns to equilibrium without any noticeable oscillations. This damping ratio is often desirable in applications where rapid or excessive vibrations are detrimental, such as in shock absorbers, suspension systems, and other vibration-sensitive equipment.
