Metoda obliczania amplitud drgań wymuszonych belek słabo tłumionych tarciem konstrukcyjnym

The object of the paper is to present vibration analysis of beams taking into account the hysteresis loops inselected modes PES. The occurence of the hysteresis phenomenon may result from Coulomb friction. The methods of finite elements and rigid finite elements are used for modelling of rea beams. The method is provided with algorithm and computer programme, with was used in the preparation of examples.
