The present note deals with the derivation of the characteristic equation of an axially vibrating viscoelastic rod (Kelvin-Voigt model), carrying a tip mass. Further, it is attempted to represent this continuous system by an '' equivalent '' spring-damper-mass system. Then, the '' first '' eigenvalues of these systems are calculated and tabulated for a wide range of the nondimensional mass parameter. (c) 2005 Elsevier Ltd. All rights reserved.
