Zusammenfassung:The present work examines damped oscillations of a chisel, represented as a distributed parameters system. The system is discretized with the finite element method. Rayleigh’s law is used for the modelling of the resistance. The internal resistance of the mechanical system has been determined by an experiment, then enshrined in the numerical model. Comparison and analysis of the results have been made.
