Forced Vibration of S.D.O.F System

Forced vibration is of two types:

  1. undamped forced vibration
  2. damped forced vibration
    Undamped forced vibration : The differential governing equation for system without damping is mü + ku = posinωt
    where, m = mass; ü = acceleration; k = stiffness; u = displacement; ωn= natural frequency; po= amplitude of force.
    Solution of the given equation is
