WebThis video explains the derivation of the frequency response function of a damped SDOF system excited by a harmonic force. Webcontinuing motion. Free and forced vibration are discussed below. FREE VIBRATION WITHOUT DAMPING Considering first the free vibration of the undamped system of Fig. 2.4, Newton’s equation is written for the mass m. The force m¨x exerted by the mass on the spring is equal and opposite to the force kx applied by the spring on the mass: m¨x ...

WebDamped Forced Vibrations. Now suppose the damping constant is positive. Again we take with , and use a trial solution . This should work since the roots of the characteristic equation will all have negative real parts. ... Thus we have seen three effects of damping on forced vibrations: It causes the solutions of the homogeneous equation to die ... WebForced Damped Vibration. The solution to a sinusoidally driven LTI system depends on the initial conditions, and is the sum of a steady state solution and a transient. Mathlet. Description. Comments.
