| Résumé: | This paper investigates the influence of longitudinal and lateral forces on
the accuracy of measurements of vertical forces for three-piece bogies. Theoretical
studies of the loading of the bogie side frame have been carried out using the finite
element method under the action of forces from a wheelset. The places of installation of
strain gauges and the method of processing the received signals are determined. A
method has been developed for measuring the vertical and lateral forces, which makes it
possible to increase the accuracy of measurements of the vertical force, with the help of
which the safety of movement is assessed during running dynamic tests and to ensure the
simultaneous measurement of vertical and lateral (frame) forces transmitted to the bogie
side frame, which will allow to reduce the number of strain gauges for measuring the
considered forces during tests. |
