Modification of modal properties of a system with non-proportional damping due to vibration absorbers and sub-soil interaction
Original language description
The paper deals with a complex linear dynamic system with proportional damping, which is completed by various elements making the final system non-proportionally damped. Such effects emerge due to vibration absorbers, soil-structure interaction and othercomponents and details. Influence of subsequently attached elements being a source of the non-proportional damping are reflected using perturbation method on the level of the first degree of a small parameter. This parameter characterizes the damping non-proportionality as the relevant perturbation. In the role of the first step the proportionally damped system is adopted. The basic system includes such a part of individual supplements to keep the proportional damping. Eigen-functions of the basic system are then used as a certain variational basis for approximate analysis of eigen-values and eigen-modes of the original system respecting non-proportionality.
