The paper presents the process of creation of a numerical model, designed for determination of the aerodynamic forces which have an impact on the pantograph. Numerical analyses were carried out in ANSYS CFX environment. The object of the study was the author's original concept model of pantograph. The values of aerodynamic forces have been computed for different velocities and heights of pantograph elevation. Furthermore, the model allowed to specify percentage of the individual elements of the pantograph on the total drag force. The values were determined by a special algorithm, which was implemented in a dynamic model of the pantograph.
