Lateral force effects of three-axle locomotive bogie on track

Abstract

This paper deals with guiding behaviour of a diesel-electric locomotive equipped with new three-axle bogies which were developed in co-operation of the company CZ LOKO and the Faculty of Transport Engineering of the University of Pardubice. At first, the design of the new bogie intended for the track gauge 1520 mm is shortly introduced. Then, the attention is paid to three different variants of secondary suspension design and their influence on lateral force effects of the locomotive on track in curves. The assessment is performed by means of the multibody simulation tool "SJKV" and it takes into account GOST standards. Possibilities of application of a system of active elements for bogie steering are also evaluated.

Cooperation of active steering control of wheelsets with subsystems of an autonomous urban rail vehicle

“…Nevertheless, a wider expansion of active elements into the running gear of rolling stock has not yet taken place. Exceptions are, for example, some Pendolino electric multiple units with active tilting of the carbody in order to reduce the lateral forces acting on the passenger when passing through a curve, or an active element placed instead of a yaw damper in the secondary suspension of Vectron locomotives in order to actively steer the bogie when passing through a curve [13]. The author of the paper discusse in detail the research on the use of active elements in RS running gear in [14].…”

Manufacturing and Calibration of Conical Springs Lateral Stiffness Meter

“…Vinita Varadharajan in [5] made a spring at the quasi-static state analytical model used as a base for haptic and visual simulation, also the author considered the analysis of vertical, shear forces, and tilting of the spring. Tomáš MICHÁLEK in [6] studied The effect of the lateral stiffness of the spring when adding rubber pads on its head, as well as finding an equation describing the lateral stiffness of the spring in the presence of pads and when the rubber pads were not present, depending on the Gross' theory. Likewise, the effect was calculated by the numerical method and the experimental method.…”
