| Abstract: | The natural vibration problem can be treated as a nonlinear eigen problem ifthe coefficient matrices of the linear vibrational system are frequency-dependent. Thispaper discusses some properties of such natural vibration problem and presents two algorithms for computing the derivatives of the Eigen data. They are useful to the optimization design of such systems. |
