✦ Synopsis

The paper concerns an n-degree of freedom damped vibrating system consisting of n!1 masses connected in parallel, by springs and dampers, to an nth mass. The paper analyzes the construction of such a system from the given complex eigenvalue data. The analysis has two parts: the establishment of the conditions on the eigenvalues which ensure that they correspond to an actual system; the derivation of the system parameters from the eigenvalues.

This experimental}theoretical paper discusses whether, and how accurately, the mass, damping and sti!ness matrices for a purportedly two-degree-of-freedom (2-d.o.f.) system may be reconstructed from the measured complex eigenvalues and/or eigenvectors. The system consists of two parallel cantilevere
