摘要：The purpose of this paper is to present methods of vibrations damping coefficient determination.The methods,such as collocation method,two energetic methods and half-power bandwidth method concern composite structures.The verification of methods has been taken into account in this work.Two real compound models and two numerical models have been created.Time series of vibrations of these models have been measured and calculated.The comparison of four methods has been made on the basis of obtained results.
