Item Research of Friction Indices Influence on the Freight Car Dynamics(Polish Academy of Sciences Branch in Lublin, Lublin, Poland, 2013) Myamlin, Sergey V.; Neduzha, Larysa O.; Ten, Alexander A.; Shvets, Angela A.EN: The work is devoted to study of friction indices influence in the "body – bogie" system in freight cars (the change of the friction coefficient in the side bearers during operation) on their basic indices – the coefficients of the horizontal and vertical dynamics, vehicle body acceleration, frame strength, and derailment stability coefficient. The study was conducted by mathematical modeling of the freight car dynamic loading using the software package «DYNRAIL». The focus was mainly concentrated on the influence of the friction force change between the body and bogies. Theoretical studies of dynamic loading of the freight open cars were conducted in both the empty and loaded conditions with the bogies model 18–100 during motion in the tangent and curved railway sections with different radii and the established motion speeds. In this case, the basic dynamic parameters of the freight car were calculated. The theoretical research results in determination of freight car dynamic indices taking into consideration the friction coefficients in the system “body – bogie” allow for an adequate assessment of the friction coefficient between the freight car bearers parameters, on the railway traffic safety factors (coefficients of dynamics, vehicle body acceleration, frame strength and derailment stability coefficient).
