Název v původním jazyce

Approximate eigen-solution of linear viscously damped system with vibration absorber

Popis výsledku v původním jazyce

Existing cantilever structures such as towers, chimneys or poles are often equipped with a damping device which suppresses undesired vibrations caused by wind load. The structure itself despite being constructed from different materials can be approximately considered as a linear classically (proportionally) damped system. It provides easier mathematical modeling and numerical calculation of modal properties and dynamic response. However, the installation of the vibration absorber into the structure could significantly change its dissipative properties and make the complete system non-proportionally damped. The eigen-solution is then more computationally intensive and can be time-consuming. In this paper an efficient approximative method for eigen-value calculation of such a type of systems is presented.
