Modal analysis allows to determine natural frequencies, modal damping ratios and mode shapes of mechanical structures. This paper presents a case study of application of the experimental modal analysis to testing of a railway car. The main purpose of the research was to determine the natural frequencies and mode shapes of the investigated object. In the paper a method of verification of the recorded measurement data quality as well as results of estimation of modal parameters are presented.
