Determination of Wheel-Rail Interaction Forces of Railway Vehicles for Evaluation of Safety Against Derailment at Running on Twisted Tracks

Part of the Mechanisms and Machine Science book series (Mechan. Machine Science,volume 95)

Abstract

Locomotives must provide a high degree of security and safety in running on any kind of railways, including twisted tracks. Safety against derailment on twisted tracks is evaluated by the limit value of the ratio between transverse guiding force, Y and vertical wheel force, Q. The paper presents a combined method for safety evaluation against derailment on twisted tracks by performing tests on a twisted test stand and on a curved and flat test railway. On the stand with twisted track is measured the minimum forces, Qa,min on the wheels of vehicle. On a curved and flat test railway, with a curve of 150 m, are measured the guiding forces of the leading wheelset. The evaluation of safety against derailment is made by calculation of ratio, (Y/Q)a, for the outer wheel of the leading wheelset. The paper presents the LE Measuring Wheelset designed for electric locomotives and calibrated for simultaneous measurements of the wheel-rail interaction forces in the vertical and transverse directions. Are also presented the tests performed by RRA Bucharest for certification, according to European Technical Specifications for Interoperability, of the LEMA 6000 kW electric locomotive, produced by Softronic Craiova-Romania, from the point of view of the safety against derailment at running on twisted tracks.
