Stress and Motion Analysis of Tram Gearbox Hinge

摘要

During working of a tram the chassis are dynamically loaded through acceleration, deceleration, passage curves and evidently by the roughness of the rail track. These added dynamic loads can significantly increase the wearing of the chassis components and drive. In the case of the tested tram problems with bearing housing into gearbox occurred. Too rigid hinge bedding can cause additional parasitic load on bearings. It is desirable to investigate its stress state during acceleration, deceleration and other common drive regimes. For this purpose, strain gauges are used. Moreover, for the verification and better description of gearbox suspension behaviour, the Qualisys system for capturing and evaluating motion is used. Acquired data are processed in the Matlab software and in the user interface of the Qualisys software.
