  1. Harmonic Oscillator

    Linked via "damping ratio"

    $$m\ddot{x} + b\dot{x} + kx = 0$$
    The behavior depends on the damping ratio ($\zeta$):
    $$\zeta = \frac{b}{2\sqrt{mk}}$$

  2. Mechanical Stability

    Linked via "damping ratio"

    Critical Damping Ratio $(\zeta)$
    For oscillating systems (e.g., suspension bridges or engine mounts), the response to an impulse is governed by the damping ratio $\zeta$.

    $$
    The FRF clearly shows resonance peaks where the denominator approaches zero (for undamped systems) or where the imaginary component of the denominator is minimized (for damped systems). Analyzing the bandwidth of these peaks allows engineers to back-calculate the damping ratios ($\zeta_i$).
