Purpose: The scope of the paper is to demonstrate the possibilities of GRAFSIM software used for modelling of vibrations of 2D and three- dimensional linearly coupled mechanical systems. Options of CATGEN application supporting the user in the transfer of data on the model generated in CATIA program to GRAFSIM are also discussed. Design/methodology/approach: For the analysis of mechanical vibrations the software applies the matrix hybrid graphs and block diagrams method. On the grounds of the data derived from the examined dynamical system and entered into the program by its user, matrices characterizing the model are generated. In the course of numerical calculations the system is represented as a block diagram, and exposed to detailed analysis in Matlab-SIMULINK environment. Findings: GRAFSIM and CATGEN software packages enable easy analyses of the vibrations of mechanical systems or of their parts. The tests may be run, for example, in view of the selection of elastic-damping connections between the inertial elements of the system. Research limitations/implications: The paper is focused on modelling of vibrating systems in the form of a passenger car. Time responses of the vibrations of the system model evoked by various types of excitations are presented, as well as the amplitude-frequency-phase characteristics (a-c-f). Originality/value: Valuable source of information for researches into the theory of mechanical vibrations searching for a tool enabling the determination of the time responses and the amplitude -frequency -phase characteristics of machine and equipment parts.
