摘要：The paper deals with determination of modal parameters by two software applications. Experimental modal analysis was performed by the commercial system Pulse® designed for vibration analysis of mechanical structures. The system was used to obtain excitation signals and corresponding response signals. The measurement data were subsequently processed in Pulse ReflexTM software and Matlab 2017, of which the signal processing toolbox provides the new functionalities specially aimed for modal analysis. The toolbox contains functions to calculate frequency response functions and to estimate modal parameters. The aim of the article is to compare the results achieved by both softwares when the first approach realized using commercial system is considered as reference. The subject of this work is to evaluate the validity of the obtained results and to point out the possibilities that the new Matlab toolbox provides.
