eng	Application of Sensitivity Analysis in Design of Characteristics of Damping Joints in Locomotive Running Gear	Operation of railway vehicles at higher speeds is conditioned by assurance of a stable run of the vehicle in straight track with a high level of geometric parameters. This property is usually reached by retrofitting of a joint between the vehicle body and the bogies with an efficient damping with suitable characteristics. Because the relative motion between the vehicle body and the bogies in the straight track shows low amplitudes and high velocities, special longitudinal dampers – so-called yaw dampers – are used for these purposes. The aim of this paper is a theoretical analysis of the yaw damper characteristics. on the stability limit of a locomotive performed by means of sensitivity analysis.	sensitivity analysis; stability of vehicle run; critical speed; yaw dampers; simulations
