A note on the damped vibrating systems

Bulatović Ranislav M. (Faculty of Mechanical Engineering, Podgorica, Montenegro)

The presence of pure imaginary eigenvalues of the partially damped vibrating systems is treated. The number of such eigenvalues is determined using the rank of a matrix which is directly related to the system matrices.

Keywords: linear system, incomplete dissipation, pure imaginary eigenvalue
