WebNatural frequency, also known as eigenfrequency, is the frequency at which a system tends to oscillate in the absence of any driving force.. The motion pattern of a system oscillating at its natural frequency is called the normal mode (if all parts of the system move sinusoidally with that same frequency).. If the oscillating system is driven by an external … WebThe solution for a critically-damped system is: x(t) = (A + Bt)e−ωnt x ( t) = ( A + B t) e − ω n t Where: A = x0 A = x 0 B = v0 + x0ωn B = v 0 + x 0 ω n 4. ζ < 1: Underdamped. c2 < 4mk c 2 < 4 m k The roots are complex numbers. Underdamped systems do oscillate around the equilibrium point.
