Analysis of a Partly Sprung Drive
Abstract
During the operation of trams in citiesthe bogies and drives are dynamically loaded through
acceleration, deceleration, passaging curves and
evidently by the roughness of the tram track. These
added dynamic loads can significantly increase the
wearing of tram drive components. The aim of this
analysis is the investigation of stress state and motions
of the gearbox hinge (support). For this purpose,
strain gauges and optical system Qualisys are used.
Special type of the strain gauges arrangement for
measuring tension and bend together is designed.
Acquired data are processed in the software Matlab
and in the user interface of the Qualisys software.
