Abstract: Method for evaluation of the stiffness of the frame body for tram car is shown with experimentally determination of the spectrum of its natural frequencies. The application of this method to determine changes in the stiffness of frame is estimated at poor welded seam.

Keywords: stiffness control, weld connection, metal frame, roof of a tram car, natural frequencies, experimental modal analysis.
