| Abstract: | The response of two-degree-of-freedom undamped systems to harmonic excitations and to general initial conditions is presented by the undetermined coefficient method. The coordinate transformation is applied to demonstrate that dynamic vibration absorbers cannot eliminate vibration of the principal system for general initial conditions. |
